如何在基于导航的应用程序中更改Push和Pop动画

Question

我有一个基于导航的应用程序，我想更改推送和弹出动画的动画。我该怎么做？

编辑2018

这个问题有很多答案，现在已经有一段时间了，我已经重新选择了我认为现在最相关的答案。如果有人不这么认为，请在评论中告诉我

Answer 1

我做了以下工作并且工作正常..并且简单易懂...

CATransition* transition = [CATransition animation];
transition.duration = 0.5;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
//transition.subtype = kCATransitionFromTop; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom
[self.navigationController.view.layer addAnimation:transition forKey:nil];
[[self navigationController] popViewControllerAnimated:NO];

推送同样的事情......

Swift 3.0版本：

let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = kCATransitionFade
self.navigationController?.view.layer.add(transition, forKey: nil)
_ = self.navigationController?.popToRootViewController(animated: false)

Answer 2

这就是我一直设法完成这项任务的方式。

推送：

MainView *nextView=[[MainView alloc] init];
[UIView  beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.75];
[self.navigationController pushViewController:nextView animated:NO];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
[UIView commitAnimations];
[nextView release];

对于Pop：

[UIView  beginAnimations:nil context:NULL];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.75];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];
[UIView commitAnimations];

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDelay:0.375];
[self.navigationController popViewControllerAnimated:NO];
[UIView commitAnimations];

我仍然从中获得了很多反馈，因此我将继续更新它以使用动画块，这无论如何都是Apple推荐的动画方式。

推送：

MainView *nextView = [[MainView alloc] init];
[UIView animateWithDuration:0.75
                         animations:^{
                             [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                             [self.navigationController pushViewController:nextView animated:NO];
                             [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
                         }];

对于Pop：

[UIView animateWithDuration:0.75
                         animations:^{
                             [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                             [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];
                         }];
[self.navigationController popViewControllerAnimated:NO];

Answer 3

推送

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionFade;
//transition.subtype = kCATransitionFromTop;

[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController pushViewController:ViewControllerYouWantToPush animated:NO];

for pop

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionFade;
//transition.subtype = kCATransitionFromTop;

[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController popViewControllerAnimated:NO];

如何在基于导航的应用中更改推送和弹出动画...

2019年，“最终答案！”

序言：

假设您是iOS开发的新手。令人困惑的是，Apple提供了两个可以轻松使用的过渡。这些是：“交叉淡化”和“翻转”。

但当然，“交叉淡化”和“翻转”都是无用的。他们从未使用过。没有人知道为什么Apple提供了这两个无用的转换！

所以：

假设您要执行普通，常见，过渡，例如“幻灯片”。在这种情况下，你必须做大量的工作！。

这项工作，在这篇文章中有解释。

重复：

令人惊讶的是：对于iOS，如果您想要最简单，最常见的日常转换（例如普通幻灯片），您必须执行所有工作 完全自定义转换。

这是怎么做的......

1。您需要自定义UIViewControllerAnimatedTransitioning

1. 你需要像popStyle一样拥有自己的布尔。 （是弹出，还是弹出？）

2. 您必须包含transitionDuration（琐碎）和主要电话animateTransition

3. 事实上， 必须 为内部animateTransition编写两个不同的例程。一个用于推送，一个用于流行音乐。可能会将其命名为animatePush和animatePop。在animateTransition内，只需将popStyle分支到两个例程

4. 以下示例执行简单的移动/移动

5. 在animatePush和animatePop例程中。您 必须 获取“从视图”和“查看”。 （如何做到这一点，在代码示例中显示。）

6. 您 必须 addSubview才能使用新的“收件人”视图。

7. 并且 必须 在动画结束时致电completeTransition

所以......

  class SimpleOver: NSObject, UIViewControllerAnimatedTransitioning {

        var popStyle: Bool = false

        func transitionDuration(
            using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
            return 0.20
        }

        func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {

            if popStyle {

                animatePop(using: transitionContext)
                return
            }

            let fz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
            let tz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!

            let f = transitionContext.finalFrame(for: tz)

            let fOff = f.offsetBy(dx: f.width, dy: 55)
            tz.view.frame = fOff

            transitionContext.containerView.insertSubview(tz.view, aboveSubview: fz.view)

            UIView.animate(
                withDuration: transitionDuration(using: transitionContext),
                animations: {
                    tz.view.frame = f
            }, completion: {_ in 
                    transitionContext.completeTransition(true)
            })
        }

        func animatePop(using transitionContext: UIViewControllerContextTransitioning) {

            let fz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
            let tz = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!

            let f = transitionContext.initialFrame(for: fz)
            let fOffPop = f.offsetBy(dx: f.width, dy: 55)

            transitionContext.containerView.insertSubview(tz.view, belowSubview: fz.view)

            UIView.animate(
                withDuration: transitionDuration(using: transitionContext),
                animations: {
                    fz.view.frame = fOffPop
            }, completion: {_ in 
                    transitionContext.completeTransition(true)
            })
        }
    }

然后......

2。在视图控制器中使用它。

注意：奇怪的是， 只需要在“第一个”视图控制器中执行此操作 。 （那个“在下面”的那个。）

使用顶部上显示的那个，执行无。容易。

所以你的班级......

class SomeScreen: UIViewController {
}

...变为

class FrontScreen: UIViewController,
        UIViewControllerTransitioningDelegate, UINavigationControllerDelegate {

    let simpleOver = SimpleOver()


    override func viewDidLoad() {

        super.viewDidLoad()
        navigationController?.delegate = self
    }

    func navigationController(
        _ navigationController: UINavigationController,
        animationControllerFor operation: UINavigationControllerOperation,
        from fromVC: UIViewController,
        to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {

        simpleOver.popStyle = (operation == .pop)
        return simpleOver
    }
}

就是这样。

正常推送和弹出，没有变化。推动......

let n = UIStoryboard(name: "nextScreenStoryboardName", bundle: nil)
          .instantiateViewController(withIdentifier: "nextScreenStoryboardID")
          as! NextScreen
navigationController?.pushViewController(n, animated: true)

然后弹出它，如果您愿意，可以在下一个屏幕上执行此操作：

class NextScreen: TotallyOrdinaryUIViewController {

    @IBAction func userClickedBackOrDismissOrSomethingLikeThat() {

        navigationController?.popViewController(animated: true)
    }
}

呼。

Answer 5

@Magnus回答，然后才对Swift（2.0）

    let transition = CATransition()
    transition.duration = 0.5
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
    transition.type = kCATransitionPush
    transition.subtype = kCATransitionFromTop
    self.navigationController!.view.layer.addAnimation(transition, forKey: nil)
    let writeView : WriteViewController = self.storyboard?.instantiateViewControllerWithIdentifier("WriteView") as! WriteViewController
    self.navigationController?.pushViewController(writeView, animated: false)

一些旁注：

您也可以使用Segue执行此操作，只需在prepareForSegue或shouldPerformSegueWithIdentifier中实现此功能即可。 然而，这也将保留默认动画。要解决此问题，您必须转到故事板，单击Segue，然后取消选中“Animates＆＃39;”框。但这会限制你的IOS 9.0及以上版本的应用程序（至少我在Xcode 7中做到了这一点）。

在segue中进行操作时，最后两行应替换为：

self.navigationController?.popViewControllerAnimated(false)

即使我设置了假，也有点忽略它。

Answer 6

请记住，在 Swift 中，扩展程序绝对是您的朋友！

public extension UINavigationController {

    /**
     Pop current view controller to previous view controller.

     - parameter type:     transition animation type.
     - parameter duration: transition animation duration.
     */
    func pop(transitionType type: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
        self.addTransition(transitionType: type, duration: duration)
        self.popViewControllerAnimated(false)
    }

    /**
     Push a new view controller on the view controllers's stack.

     - parameter vc:       view controller to push.
     - parameter type:     transition animation type.
     - parameter duration: transition animation duration.
     */
    func push(viewController vc: UIViewController, transitionType type: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
        self.addTransition(transitionType: type, duration: duration)
        self.pushViewController(vc, animated: false)
    }

    private func addTransition(transitionType type: String = kCATransitionFade, duration: CFTimeInterval = 0.3) {
        let transition = CATransition()
        transition.duration = duration
        transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition.type = type
        self.view.layer.addAnimation(transition, forKey: nil)
    }

}

Answer 7

使用私人电话是一个坏主意，因为Apple不再批准那样做的应用程序。 也许你可以试试这个：

//Init Animation
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration: 0.50];


[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.navigationController.view cache:YES];

//Create ViewController
MyViewController *myVC = [[MyViewController alloc] initWith...];

[self.navigationController pushViewController:myVC animated:NO];
[myVC release];

//Start Animation
[UIView commitAnimations];

Answer 8

由于这是Google的最高成绩，我认为我会分享我认为最健全的方式;这是使用iOS 7+转换API。我使用Swift 3为iOS 10实现了这个。

如果您创建UINavigationController的子类并返回符合UINavigationController协议的类的实例，那么将它与UIViewControllerAnimatedTransitioning两个视图控制器之间的动画结合起来非常简单。

例如，这是我的UINavigationController子类：

class NavigationController: UINavigationController {
    init() {
        super.init(nibName: nil, bundle: nil)

        delegate = self
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

extension NavigationController: UINavigationControllerDelegate {

    public func navigationController(_ navigationController: UINavigationController, animationControllerFor operation: UINavigationControllerOperation, from fromVC: UIViewController, to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        return NavigationControllerAnimation(operation: operation)
    }

}

您可以看到我将UINavigationControllerDelegate设置为自身，并且在我的子类的扩展中，我实现了UINavigationControllerDelegate中允许您返回自定义动画控制器的方法（即{{1} }}）。此自定义动画控制器将替换您的股票动画。

您可能想知道为什么我通过其初始化程序将操作传递给NavigationControllerAnimation实例。我这样做是为了在NavigationControllerAnimation NavigationControllerAnimation协议的实现中我知道操作是什么（即'push'或'pop'）。这有助于了解我应该做什么样的动画。大多数情况下，您希望根据操作执行不同的动画。

其余的很标准。在UIViewControllerAnimatedTransitioning协议中实现两个必需的函数，然后按照您喜欢的方式设置动画：

UIViewControllerAnimatedTransitioning

重要的是要记住，对于每种不同类型的操作（即“推”或“弹出”），来往视图控制器将是不同的。当您处于推送操作时，视图控制器将被推送。当您处于弹出操作时，视图控制器将是正在转换到的控制器，并且视图控制器将是正在弹出的控制器。

此外，必须将class NavigationControllerAnimation: NSObject, UIViewControllerAnimatedTransitioning { let operation: UINavigationControllerOperation init(operation: UINavigationControllerOperation) { self.operation = operation super.init() } func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval { return 0.3 } public func animateTransition(using transitionContext: UIViewControllerContextTransitioning) { guard let fromViewController = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from), let toViewController = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to) else { return } let containerView = transitionContext.containerView if operation == .push { // do your animation for push } else if operation == .pop { // do your animation for pop } } } 视图控制器添加为转换上下文中to的子视图。

动画完成后，您必须致电containerView。如果您正在进行交互式转换，则必须动态地将transitionContext.completeTransition(true)返回到Bool，具体取决于动画结束时转换是否完成。

最后（可选阅读），您可能想看看我是如何完成我正在进行的转换。这段代码有点笨拙，我写的很快，所以我不会说它是伟大的动画代码，但它仍然显示了如何做动画部分。

我的过渡非常简单;我想模仿UINavigationController通常所做的相同动画，但是我想要在新视图的同时实现旧视图控制器的1：1动画，而不是它的“顶部下一页”动画。控制器出现。这样可以使两个视图控制器看起来像彼此固定一样。

对于推送操作，需要首先在x轴关闭屏幕上设置completeTransition(didComplete: Bool)的视图原点，将其添加为toViewController的子视图，通过设置该动画将其设置为屏幕上的动画containerView为零。同时，我通过在屏幕上设置origin.x来为fromViewController的视图添加动画效果：

origin.x

弹出操作基本上是相反的。将toViewController.view.frame = containerView.bounds.offsetBy(dx: containerView.frame.size.width, dy: 0.0) containerView.addSubview(toViewController.view) UIView.animate(withDuration: transitionDuration(using: transitionContext), delay: 0, options: [ UIViewAnimationOptions.curveEaseOut ], animations: { toViewController.view.frame = containerView.bounds fromViewController.view.frame = containerView.bounds.offsetBy(dx: -containerView.frame.size.width, dy: 0) }, completion: { (finished) in transitionContext.completeTransition(true) }) 添加为toViewController的子视图，并在左侧containerView动画时向右边的fromViewController设置动画：

toViewController

以下是整个swift文件的要点：

Answer 9

在那里有UINavigationControllerDelegate和UIViewControllerAnimatedTransition，您可以根据需要更改动画。

例如，这是VC的垂直弹出动画：

@objc class PopAnimator: NSObject, UIViewControllerAnimatedTransitioning {

func transitionDuration(transitionContext: UIViewControllerContextTransitioning?) -> NSTimeInterval {
    return 0.5
}

func animateTransition(transitionContext: UIViewControllerContextTransitioning) {

    let fromViewController = transitionContext.viewControllerForKey(UITransitionContextFromViewControllerKey)!
    let toViewController = transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)!
    let containerView = transitionContext.containerView()
    let bounds = UIScreen.mainScreen().bounds
    containerView!.insertSubview(toViewController.view, belowSubview: fromViewController.view)
    toViewController.view.alpha = 0.5

    let finalFrameForVC = fromViewController.view.frame

    UIView.animateWithDuration(transitionDuration(transitionContext), animations: {
        fromViewController.view.frame = CGRectOffset(finalFrameForVC, 0, bounds.height)
        toViewController.view.alpha = 1.0
        }, completion: {
            finished in
            transitionContext.completeTransition(!transitionContext.transitionWasCancelled())
    })
}

}

然后

func navigationController(navigationController: UINavigationController, animationControllerForOperation operation: UINavigationControllerOperation, fromViewController fromVC: UIViewController, toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    if operation == .Pop {
        return PopAnimator()
    }
    return nil;
}

Answer 10

基于更新为swift 4的jordanperry answer

推送UIViewController

let yourVC = self.storyboard?.instantiateViewController(withIdentifier: "yourViewController") as! yourViewController
    UIView.animate(withDuration: 0.75, animations: {() -> Void in
    UIView.setAnimationCurve(.easeInOut)
    self.navigationController?.pushViewController(terms, animated: true)
    UIView.setAnimationTransition(.flipFromRight, for: (self.navigationController?.view)!, cache: false)
})

对于Pop

UIView.animate(withDuration: 0.75, animations: {() -> Void in
    UIView.setAnimationCurve(.easeInOut)
    UIView.setAnimationTransition(.flipFromLeft, for: (self.navigationController?.view)!, cache: false)
})
navigationController?.popViewController(animated: false)

Answer 11

以下是我在Swift中做同样的事情：

推送：

    UIView.animateWithDuration(0.75, animations: { () -> Void in
        UIView.setAnimationCurve(UIViewAnimationCurve.EaseInOut)
        self.navigationController!.pushViewController(nextView, animated: false)
        UIView.setAnimationTransition(UIViewAnimationTransition.FlipFromRight, forView: self.navigationController!.view!, cache: false)
    })

对于Pop：

我实际上对上面的一些响应做了一点点不同 - 但由于我是Swift开发的新手，它可能不对。我已覆盖viewWillDisappear:animated:并在其中添加了pop代码：

    UIView.animateWithDuration(0.75, animations: { () -> Void in
        UIView.setAnimationCurve(UIViewAnimationCurve.EaseInOut)
        UIView.setAnimationTransition(UIViewAnimationTransition.FlipFromLeft, forView: self.navigationController!.view, cache: false)
    })

    super.viewWillDisappear(animated)

Answer 12

我最近试图做类似的事情。我决定不喜欢UINavigationController的滑动动画，但我也不想做UIView给你的动画像curl或类似的东西。当我推或弹时，我想在视图之间进行交叉淡入淡出。

那里的问题涉及这样的事实：视图实际上是删除视图或在当前视图的顶部弹出一个视图，因此淡入淡出不起作用。我参与的解决方案包括获取我的新视图并将其作为子视图添加到UIViewController堆栈上的当前顶视图。我用alpha为0添加它，然后进行交叉渐变。当动画序列完成时，我将视图推送到堆栈而不动画。然后我回到旧的topView并清理我已经改变的东西。

它比这更复杂，因为你必须调整navigationItems以使转换看起来正确。此外，如果进行任何旋转，则必须在将视图添加为子视图时调整帧大小，以便它们在屏幕上正确显示。这是我使用的一些代码。我将UINavigationController子类化，并覆盖push和pop方法。

-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
      UIViewController *currentViewController = [self.viewControllers lastObject];
      //if we don't have a current controller, we just do a normal push
      if(currentViewController == nil)
      {
         [super pushViewController:viewController animated:animated];
         return;
      }
      //if no animation was requested, we can skip the cross fade
      if(!animation)
      {
         [super pushViewController:viewController animated:NO];
         return;
      }
      //start the cross fade.  This is a tricky thing.  We basically add the new view
//as a subview of the current view, and do a cross fade through alpha values.
//then we push the new view on the stack without animating it, so it seemlessly is there.
//Finally we remove the new view that was added as a subview to the current view.

viewController.view.alpha = 0.0;
//we need to hold onto this value, we'll be releasing it later
    NSString *title = [currentViewController.title retain];

//add the view as a subview of the current view
[currentViewController.view addSubview:viewController.view];
[currentViewController.view bringSubviewToFront:viewController.view];
UIBarButtonItem *rButtonItem = currentViewController.navigationItem.rightBarButtonItem;
UIBarButtonItem *lButtonItem = currentViewController.navigationItem.leftBarButtonItem;

NSArray *array = nil;

//if we have a right bar button, we need to add it to the array, if not, we will crash when we try and assign it
//so leave it out of the array we are creating to pass as the context.  I always have a left bar button, so I'm not checking to see if it is nil. Its a little sloppy, but you may want to be checking for the left BarButtonItem as well.
if(rButtonItem != nil)
    array = [[NSArray alloc] initWithObjects:currentViewController,viewController,title,lButtonItem,rButtonItem,nil];
else {
    array = [[NSArray alloc] initWithObjects:currentViewController,viewController,title,lButtonItem,nil];
}

//remove the right bar button for our transition
[currentViewController.navigationItem setRightBarButtonItem:nil animated:YES];
//remove the left bar button and create a backbarbutton looking item
//[currentViewController.navigationItem setLeftBarButtonItem:nil animated:NO];

//set the back button
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:title style:kButtonStyle target:self action:@selector(goBack)];
[currentViewController.navigationItem setLeftBarButtonItem:backButton animated:YES];
[viewController.navigationItem setLeftBarButtonItem:backButton animated:NO];
[backButton release];

[currentViewController setTitle:viewController.title];

[UIView beginAnimations:@"push view" context:array];
[UIView setAnimationDidStopSelector:@selector(animationForCrossFadePushDidStop:finished:context:)];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:0.80];
[viewController.view setAlpha: 1.0];
[UIView commitAnimations];
}

-(void)animationForCrossFadePushDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
{

UIViewController *c = [(NSArray*)context objectAtIndex:0];
UIViewController *n = [(NSArray*)context objectAtIndex:1];
NSString *title     = [(NSArray *)context objectAtIndex:2];
UIBarButtonItem *l = [(NSArray *)context objectAtIndex:3];
UIBarButtonItem *r = nil;
//not all views have a right bar button, if we look for it and it isn't in the context,
//we'll crash out and not complete the method, but the program won't crash.
//So, we need to check if it is there and skip it if it isn't.
if([(NSArray *)context count] == 5)
    r = [(NSArray *)context objectAtIndex:4];

//Take the new view away from being a subview of the current view so when we go back to it
//it won't be there anymore.
[[[c.view subviews] lastObject] removeFromSuperview];
[c setTitle:title];
[title release];
//set the search button
[c.navigationItem setLeftBarButtonItem:l animated:NO];
//set the next button
if(r != nil)
    [c.navigationItem setRightBarButtonItem:r animated:NO];


[super pushViewController:n animated:NO];

 }

正如我在代码中提到的，我总是有一个左栏按钮项，所以在将它作为动画委托的上下文传递给数组之前，我不检查它是否为nil。如果您这样做，您可能想要进行检查。

我发现的问题是，如果你在委托方法中崩溃，它不会崩溃程序。它只是阻止代表完成但你没有收到任何警告 所以，因为我在该委托例程中进行了清理，所以它导致了一些奇怪的视觉行为，因为它没有完成清理。

我创建的后退按钮调用“goBack”方法，该方法只调用pop例程。

-(void)goBack
{ 
     [self popViewControllerAnimated:YES];
}

此外，这是我的流行例程。

-(UIViewController *)popViewControllerAnimated:(BOOL)animated
{
    //get the count for the number of viewControllers on the stack
int viewCount = [[self viewControllers] count];
//get the top view controller on the stack
UIViewController *topViewController = [self.viewControllers objectAtIndex:viewCount - 1];
//get the next viewController after the top one (this will be the new top one)
UIViewController *newTopViewController = [self.viewControllers objectAtIndex:viewCount - 2];

//if no animation was requested, we can skip the cross fade
if(!animated)
{
    [super popViewControllerAnimated:NO];
            return topViewController;
}



//start of the cross fade pop.  A bit tricky.  We need to add the new top controller
//as a subview of the curent view controler with an alpha of 0.  We then do a cross fade.
//After that we pop the view controller off the stack without animating it.
//Then the cleanup happens: if the view that was popped is not released, then we
//need to remove the subview we added and change some titles back.
newTopViewController.view.alpha = 0.0;
[topViewController.view addSubview:newTopViewController.view];
[topViewController.view bringSubviewToFront:newTopViewController.view];
NSString *title = [topViewController.title retain];
UIBarButtonItem *lButtonItem = topViewController.navigationItem.leftBarButtonItem;
UIBarButtonItem *rButtonItem = topViewController.navigationItem.rightBarButtonItem;

//set the new buttons on top of the current controller from the new top controller
if(newTopViewController.navigationItem.leftBarButtonItem != nil)
{
    [topViewController.navigationItem setLeftBarButtonItem:newTopViewController.navigationItem.leftBarButtonItem animated:YES];
}
if(newTopViewController.navigationItem.rightBarButtonItem != nil)
{
    [topViewController.navigationItem setRightBarButtonItem:newTopViewController.navigationItem.rightBarButtonItem animated:YES];
}

[topViewController setTitle:newTopViewController.title];

这就是它。如果要实现旋转，则需要一些额外的代码。您需要在显示之前设置您添加为子视图的视图的帧大小，否则您将遇到方向为横向的问题，但上次您看到上一个视图时它是纵向的。所以，然后你将它添加为子视图并淡入它但它显示为肖像，然后当我们弹出没有动画时，相同的视图，但堆栈中的那个，现在是风景。整件事看起来有点时髦。每个人的轮换实现都有点不同，所以我没有在这里包含我的代码。

希望它可以帮助一些人。我一直在寻找这样的东西，却找不到任何东西。我认为这不是一个完美的答案，但在这一点上它对我来说真的很有效。

Answer 13

使用iJordan的答案作为灵感，为什么不简单地在UINavigationController上创建一个分类，以便在整个应用中使用，而不是在整个地方复制/粘贴这个动画代码？

的UINavigationController + Animation.h

@interface UINavigationController (Animation)

- (void) pushViewControllerWithFlip:(UIViewController*) controller;

- (void) popViewControllerWithFlip;

@end

的UINavigationController + Animation.m

@implementation UINavigationController (Animation)

- (void) pushViewControllerWithFlip:(UIViewController *) controller
{
    [UIView animateWithDuration:0.50
                     animations:^{
                         [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                         [self pushViewController:controller animated:NO];
                         [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:NO];
                     }];
}

- (void) popViewControllerWithFlip
{
    [UIView animateWithDuration:0.5
                     animations:^{
                         [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                         [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:NO];
                     }];

    [self popViewControllerAnimated:NO];
}

@end

然后只需导入UINavigationController + Animation.h文件并正常调用它：

[self.navigationController pushViewControllerWithFlip:[[NewViewController alloc] init]];

[self.navigationController popViewControllerWithFlip];

Answer 14

您现在可以使用UIView.transition。请注意animated:false。这适用于任何转换选项，弹出，推送或堆栈替换。

if let nav = self.navigationController
{
    UIView.transition(with:nav.view, duration:0.3, options:.transitionCrossDissolve, animations: {
        _ = nav.popViewController(animated:false)
    }, completion:nil)
}

Answer 15

看看ADTransitionController，我们在Applidium创建的自定义转换动画（它的API与UINavigationController的API匹配）是UINavigationController的替代品。

您可以为推送和流行操作使用不同的预定义动画，例如刷卡，淡化， 多维数据集，卡鲁塞尔，缩放等。

Answer 16

虽然这里的所有答案都很棒，而且大部分工作都很顺利，但是有一种稍微简单的方法可以达到同样的效果......

推送：

  NextViewController *nextViewController = [[NextViewController alloc] init];

  // Shift the view to take the status bar into account 
  CGRect frame = nextViewController.view.frame;
  frame.origin.y -= 20;
  frame.size.height += 20;
  nextViewController.view.frame = frame;

  [UIView transitionFromView:self.navigationController.topViewController.view toView:nextViewController.view duration:0.5 options:UIViewAnimationOptionTransitionFlipFromRight completion:^(BOOL finished) {
    [self.navigationController pushViewController:nextViewController animated:NO];
  }];

对于Pop：

  int numViewControllers = self.navigationController.viewControllers.count;
  UIView *nextView = [[self.navigationController.viewControllers objectAtIndex:numViewControllers - 2] view];

  [UIView transitionFromView:self.navigationController.topViewController.view toView:nextView duration:0.5 options:UIViewAnimationOptionTransitionFlipFromLeft completion:^(BOOL finished) {
    [self.navigationController popViewControllerAnimated:NO];
  }];}

Answer 17

非常简单

self.navigationController?.view.semanticContentAttribute = .forceRightToLeft

Answer 18

请参阅我的回答to this question，了解在更少的代码行中执行此操作的方法。此方法允许您以任何方式为新视图控制器的伪“推”设置动画，并且在动画完成后，它将设置导航控制器，就像您使用标准Push方法一样。我的示例允许您从左侧或右侧为幻灯片设置动画。 为方便起见，此处重复了代码：

-(void) showVC:(UIViewController *) nextVC rightToLeft:(BOOL) rightToLeft {
    [self addChildViewController:neighbor];
    CGRect offscreenFrame = self.view.frame;
    if(rightToLeft) {
        offscreenFrame.origin.x = offscreenFrame.size.width * -1.0;
    } else if(direction == MyClimbDirectionRight) {
        offscreenFrame.origin.x = offscreenFrame.size.width;
    }
    [[neighbor view] setFrame:offscreenFrame];
    [self.view addSubview:[neighbor view]];
    [neighbor didMoveToParentViewController:self];
    [UIView animateWithDuration:0.5 animations:^{
        [[neighbor view] setFrame:self.view.frame];
    } completion:^(BOOL finished){
        [neighbor willMoveToParentViewController:nil];
        [neighbor.view removeFromSuperview];
        [neighbor removeFromParentViewController];
        [[self navigationController] pushViewController:neighbor animated:NO];
        NSMutableArray *newStack = [[[self navigationController] viewControllers] mutableCopy];
        [newStack removeObjectAtIndex:1]; //self, just below top
        [[self navigationController] setViewControllers:newStack];
    }];
}

Answer 20

我不知道您可以公开更改过渡动画的任何方式。

如果不需要“后退”按钮，应使用modal view controllers进行“从底部推”/“翻转”/“淡入淡出”/（≥3.2）“页面卷曲“过渡。

---

在私有方面，方法-pushViewController:animated:会调用未记录的方法-pushViewController:transition:forceImmediate:，例如如果您想要从左到右翻转，可以使用

[navCtrler pushViewController:ctrler transition:10 forceImmediate:NO];

但是，你不能以这种方式改变“弹出”过渡。

Answer 21

意识到这是一个老问题。我仍然想发布这个答案，因为我有一些问题突然出现了几个viewControllers的答案。我的解决方案是子类UINavigationController并覆盖所有pop和push方法。

FlippingNavigationController.h

@interface FlippingNavigationController : UINavigationController

@end

FlippingNavigationController.m：

#import "FlippingNavigationController.h"

#define FLIP_DURATION 0.5

@implementation FlippingNavigationController

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    [UIView transitionWithView:self.view
                      duration:animated?FLIP_DURATION:0
                       options:UIViewAnimationOptionCurveEaseInOut | UIViewAnimationOptionTransitionFlipFromRight
                    animations:^{ [super pushViewController:viewController
                                                   animated:NO]; }
                    completion:nil];
}

- (UIViewController *)popViewControllerAnimated:(BOOL)animated
{
    return [[self popToViewController:[self.viewControllers[self.viewControllers.count - 2]]
                             animated:animated] lastObject];
}

- (NSArray *)popToRootViewControllerAnimated:(BOOL)animated
{
    return [self popToViewController:[self.viewControllers firstObject]
                            animated:animated];
}

- (NSArray *)popToViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    __block NSArray* viewControllers = nil;

    [UIView transitionWithView:self.view
                      duration:animated?FLIP_DURATION:0
                       options:UIViewAnimationOptionCurveEaseInOut | UIViewAnimationOptionTransitionFlipFromLeft
                    animations:^{ viewControllers = [super popToViewController:viewController animated:NO]; }
                    completion:nil];

    return viewControllers;
}

Answer 22

只需使用：

ViewController *viewController = [[ViewController alloc] init];

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
navController.navigationBarHidden = YES;

[self presentViewController:navController animated:YES completion: nil];
[viewController release];
[navController release];

从示例应用中，查看此变体。 https://github.com/mpospese/MPFoldTransition/

我知道这个线程很旧，但是我以为我要花两美分。您不需要制作自定义动画，这是一种简单的方法（也许很笨拙）。代替使用推，创建一个新的导航控制器，使新的视图控制器成为该导航控制器的根视图控制器，然后从原始导航控制器中显示该导航控制器。 Present可以很容易地自定义为多种样式，而无需制作自定义动画。

例如：

Sub Macro15()
'
' Macro15 Macro
'
' Keyboard Shortcut: Ctrl+Shift+Q
'
    Sheets("MACRO (insert data)").Select
    Range("G4:Q4").Select
    Selection.Copy
    Sheets("Jun-2019").Select
    Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False
    Sheets("MACRO (insert data)").Select
    Range("W4:AG5").Select
    Selection.Copy
    Sheets("Jun-2019").Select
    Range("C42").Select
    Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False
    Range("O10:Y10").Select
    Selection.Copy
    Startcell.Offset(0, 11).Select
    Selection.PasteSpecial Paste:=xlPasteFormulas, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False

End Sub

您可以根据需要更改演示样式。

Answer 25

我找到了一种温和的递归方式来实现这个目的。我有一个实例变量BOOL，用于阻止正常的弹出动画并替换我自己的非动画弹出消息。该变量最初设置为NO。当点击后退按钮时，委托方法将其设置为YES并向导航栏发送新的非动画弹出消息，从而再次调用相同的委托方法，这次将变量设置为YES。将变量设置为YES时，委托方法将其设置为NO并返回YES以允许发生非动画弹出。第二个委托调用返回后，我们最终返回第一个，返回NO，阻止原始动画弹出！它实际上没有听起来那么混乱。我的shouldPopItem方法如下所示：

- (BOOL)navigationBar:(UINavigationBar *)navigationBar shouldPopItem:(UINavigationItem *)item 
{
    if ([[navigationBar items] indexOfObject:item] == 1) 
    {
        [expandedStack restack];    
    }

    if (!progPop) 
    {
        progPop = YES;
        [navBar popNavigationItemAnimated:NO];
        return NO;
    }
    else 
    {
        progPop = NO;
        return YES;
    }
}

适合我。
