Question

是否可以在Storyboard中的视图控制器之间进行淡入和淡出过渡。或者没有过渡。

如果有可能，它的代码是什么？

Answer 1

如果展示模态视图控制器，您可以指定modalTransitionStyle UIModalTransitionStyleCrossDissolve。如果在故事板中使用segue执行此操作，请选择segue的属性检查器，并在那里指定过渡样式：

enter image description here

如果以编程方式呈现视图控制器，您可以在故事板中的视图控制器之间使用“Cross Dissolve”的“Transition”定义模态segue，然后让源视图控制器执行此segue：

[self performSegueWithIdentifier:@"presentSegue" sender:sender];

或者，如果您致电presentViewController：

UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"YourStoryboardID"];
controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentViewController:controller animated:YES completion:nil];

在iOS 7中，Apple提供了一项新技术，可为高度自定义的过渡提供丰富而强大的控制。有关更多信息，请参阅WWDC 2013视频Custom Transitions Using View Controllers。

但是，例如，如果要将iOS 7中的推送和弹出动画自定义为淡入淡出，则应为导航控制器指定delegate

- (void)viewDidLoad {
    [super viewDidLoad];

    self.navigationController.delegate = self;
}

然后，您将实现animationControllerForOperation指定动画对象以进行推送和弹出：

- (id<UIViewControllerAnimatedTransitioning>)navigationController:(UINavigationController *)navigationController
                                  animationControllerForOperation:(UINavigationControllerOperation)operation
                                               fromViewController:(UIViewController*)fromVC
                                                 toViewController:(UIViewController*)toVC
{
    if (operation == UINavigationControllerOperationPush)
        return [[PushAnimator alloc] init];

    if (operation == UINavigationControllerOperationPop)
        return [[PopAnimator alloc] init];

    return nil;
}

您显然必须实现自定义推送和弹出动画制作工具，例如：

@interface PushAnimator : NSObject <UIViewControllerAnimatedTransitioning>

@end

@implementation PushAnimator

- (NSTimeInterval)transitionDuration:(id <UIViewControllerContextTransitioning>)transitionContext
{
    return 0.5;
}

- (void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext
{
    UIViewController* toViewController   = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];

    [[transitionContext containerView] addSubview:toViewController.view];

    toViewController.view.alpha = 0.0;

    [UIView animateWithDuration:[self transitionDuration:transitionContext] animations:^{
        toViewController.view.alpha = 1.0;
    } completion:^(BOOL finished) {
        [transitionContext completeTransition:![transitionContext transitionWasCancelled]];
    }];
}

@end

和

@interface PopAnimator : NSObject <UIViewControllerAnimatedTransitioning>

@end

@implementation PopAnimator

- (NSTimeInterval)transitionDuration:(id <UIViewControllerContextTransitioning>)transitionContext
{
    return 0.5;
}

- (void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext
{
    UIViewController* toViewController   = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
    UIViewController* fromViewController = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];

    [[transitionContext containerView] insertSubview:toViewController.view belowSubview:fromViewController.view];

    [UIView animateWithDuration:[self transitionDuration:transitionContext] animations:^{
        fromViewController.view.alpha = 0.0;
    } completion:^(BOOL finished) {
        [transitionContext completeTransition:![transitionContext transitionWasCancelled]];
    }];
}

@end

自定义模态过渡也有类似但略有不同的技术（尽管如果你只是做一张脸，你可能只是使用上面讨论的modalTransitionStyle，除非你有其他微妙的定制你想雇用）。有关详细信息，请参阅上述Custom Transitions Using View Controllers。

底线，iOS 7的自定义过渡是一种稍微复杂但非常强大的方式，可以对过渡动画提供巨大的控制。

Answer 2

用于创建自定义分段创建UIStoryboard segue的子类。例如：

// MCFadeSegue.h
#import <UIKit/UIKit.h>

@interface MCFadeSegue : UIStoryboardSegue

@end

// MCFadeSegue.m
#import <QuartzCore/QuartzCore.h>
#import "MCFadeSegue.h"

@implementation MCFadeSegue

- (void)perform
{
  CATransition *transition = [CATransition animation];
  transition.duration = 0.5;
  transition.type = kCATransitionFade;

  [[[[[self sourceViewController] view] window] layer] addAnimation:transition
      forKey:kCATransitionFade];

  [[self sourceViewController]
      presentViewController:[self destinationViewController]
      animated:NO completion:NULL];
}

@end

然后在MainStoryboard.storyboard中选择segue并设置Style：Custom和Class：MCFadeSegue。

Answer 3

在Swift中推送/弹出UIVIewController FadeIn / FadeOut

class FadeInPushSegue: UIStoryboardSegue {

    var animated: Bool = true

    override func perform() {

        if var sourceViewController = self.sourceViewController as? UIViewController, var destinationViewController = self.destinationViewController as? UIViewController {

            var transition: CATransition = CATransition()

            transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
            sourceViewController.view.window?.layer.addAnimation(transition, forKey: "kCATransition")
            sourceViewController.navigationController?.pushViewController(destinationViewController, animated: false)


        }
    }

}

class FadeOutPopSegue: UIStoryboardSegue {

    override func perform() {

        if var sourceViewController = self.sourceViewController as? UIViewController, var destinationViewController = self.destinationViewController as? UIViewController {

            var transition: CATransition = CATransition()

            transition.duration = 0.4
            transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
            transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade

            sourceViewController.view.window?.layer.addAnimation(transition, forKey: "kCATransition")
            sourceViewController.navigationController?.popViewControllerAnimated(false)
        }
    }

}

Answer 4

无需创建自定义segue，我将此代码放在一起以呈现视图...

UIViewController *nextView = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"YOUR_VIEW_CONTROLLER_STORYBOARD_NAME"];

nextView.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;

[self.navigationController presentViewController:nextView animated:YES completion:nil];
// (For a cross dissolve, set animated:YES.  For no transition, set animated:NO.)

希望这有助于任何遇到此问题的人！

Answer 5

试试这个。

    let transition: CATransition = CATransition()
    transition.duration = 0.4
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
    transition.type = kCATransitionFade
    self.navigationController!.view.layer.addAnimation(transition, forKey: nil)

    let vc = self.storyboard?.instantiateViewControllerWithIdentifier("vcID") as! My_ViewController
    self.navigationController?.pushViewController(vc, animated: false)

Answer 6

我的Swift版本，带有可选的检查功能！

    let storyboard = UIStoryboard.init(name: "Main", bundle: nil)
    if let stView = storyboard.instantiateViewControllerWithIdentifier("STVC") as? STVC {
        stView.modalTransitionStyle = UIModalTransitionStyle.CrossDissolve
        self.navigationController?.presentViewController(stView, animated: true, completion: nil)
    }

只需确保设置＆＃34; View控制器＆＃34;的故事板ID。在IB

Answer 7

我所做的是在Interface Builder中使用Storyboard，连接你需要移动到/从和移回的两个视图控制器（按住ctrl并从原点视图控制器拖动单击到目标视图控制器），并更改了segue属性。我使用了以下内容：

然后我使用了以下内容：

[self performSegueWithIdentifier:@"showMovieDetailSegue" sender:self];

如果要删除它，只需从origin viewcontroller中调用它：

[self dismissViewControllerAnimated:YES completion:nil];

简单快捷。

根据Eugene Braginets＆＃39; s answer

以 Swift 3 语法推送/弹出UIVIewController FadeIn / FadeOut

class FadeInPushSegue: UIStoryboardSegue {

    var animated: Bool = true

    override func perform() {

        let sourceViewController = self.source
        let destinationViewController = self.destination

        let transition: CATransition = CATransition()

        transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
        sourceViewController.view.window?.layer.add(transition, forKey: "kCATransition")
        sourceViewController.navigationController?.pushViewController(destinationViewController, animated: false)

    }

}

class FadeOutPopSegue: UIStoryboardSegue {

    override func perform() {

        let sourceViewController = self.source

        let transition: CATransition = CATransition()

        transition.duration = 0.4
        transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade

        sourceViewController.view.window?.layer.add(transition, forKey: "kCATransition")
        _ = sourceViewController.navigationController?.popViewController(animated: false)
    }

}

Answer 9

这使我疯了几个小时。这些解决方案似乎都不是我想要的，而且我已经失去了理智。最终提出了以下内容，它使用淡入/淡入过渡在单个NSWindow中交换视图控制器。首先，它执行淡出操作，然后在完成处理程序中，将窗口的视图设置为新视图并执行淡入操作。也许有更好的方法可以做到这一点，但这是我可以共同破解的最简单方法

class CustomSegue : NSStoryboardSegue {
    override func perform() {
        guard let fromController = sourceController as? NSViewController else {
            return;
        }
        guard let toController = destinationController as? NSViewController else {
            return;
        }
        let animationDuration = 0.5;
        NSAnimationContext.runAnimationGroup({
            $0.duration = animationDuration;
            fromController.view.animator().alphaValue = 0.0;
        }, completionHandler: {
            fromController.view.window?.contentViewController = toController;
            toController.view.alphaValue = 0.0;
            NSAnimationContext.runAnimationGroup({
                $0.duration = animationDuration;
                toController.view.animator().alphaValue = 1.0;
            })
        });

    }
}

Apple文档中缺少示例，这使我想动脑筋，Objective C和Swift的混合使用只是……ba！

快捷键5：

花了数小时寻找合适的解决方案Rob's之后，一个人满足了我的所有需求，经过一些调整，它是完美的。

创建淡入淡出的View Controller类：

class FadeViewControllerTransition: NSObject, UIViewControllerAnimatedTransitioning {
    
    var fadeOut: Bool = false
    
    func transitionDuration(
        using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
        return 0.5
    }
    
    func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
        
        if fadeOut {
            animateFadeOut(using: transitionContext)
            return
        }
        
        let toViewController = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
        transitionContext.containerView.addSubview(toViewController.view)
        toViewController.view.alpha = 0.0
        UIView.animate(withDuration: transitionDuration(using: transitionContext), animations: {
            toViewController.view.alpha = 1.0
        }, completion: { _ in
            transitionContext.completeTransition(!transitionContext.transitionWasCancelled)
        })
    }
    
    func animateFadeOut(using transitionContext: UIViewControllerContextTransitioning) {
        
        let toViewController = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
        let fromViewController = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
        transitionContext.containerView.insertSubview(toViewController.view, belowSubview: fromViewController.view)
        UIView.animate(withDuration: transitionDuration(using: transitionContext), animations: {
            fromViewController.view.alpha = 0.0
        }, completion: { _ in
            transitionContext.completeTransition(!transitionContext.transitionWasCancelled)
        })
    }
}

在导航控制器的第一个View Controller中：

class MainViewController: UIViewController, UIViewControllerTransitioningDelegate, UINavigationControllerDelegate {

    private let fadeVCTransition = FadeViewControllerTransition()
    
    func navigationController(_ navigationController: UINavigationController, animationControllerFor operation: UINavigationController.Operation, from fromVC: UIViewController, to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        fadeVCTransition.fadeOut = (operation == .pop)
        return fadeVCTransition
    }

就是这样。
