Question

众所周知，UINavigationController从左到右推送ViewController，有没有办法将视图从右推到左？就像后退按钮的动画一样现在我有这个：


[self.navigationController pushViewController:viewController animated:YES];

Answer 1

您可以从navigationController的NSMutableArray数组中创建viewcontrollers，并在当前版本之前插入新的viewController。然后设置viewControllers数组没有动画并弹回。

UIViewController *newVC = ...;
NSMutableArray *vcs =  [NSMutableArray arrayWithArray:self.navigationController.viewControllers];
[vcs insertObject:newVC atIndex:[vcs count]-1];
[self.navigationController setViewControllers:vcs animated:NO];
[self.navigationController popViewControllerAnimated:YES];

Answer 2

请尝试这个

HomePageController  *pageView = [[HomePageController alloc] initWithNibName:@"HomePageController_iPhone" bundle:nil];

CATransition *transition = [CATransition animation];
transition.duration = 0.45;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;
transition.delegate = self;
[self.navigationController.view.layer addAnimation:transition forKey:nil];

self.navigationController.navigationBarHidden = NO;
[self.navigationController pushViewController:pageView animated:NO];

Answer 3

Try this :  
//Push effect in reverse way
    CATransition* transition = [CATransition animation];
    transition.duration = 0.75;
    transition.type = kCATransitionPush;
    transition.subtype = kCATransitionFromLeft;
    [self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
    [self.navigationController pushViewController:vc animated:NO];

Answer 4

此代码工作正常。请尝试

CATransition *transition = [CATransition animation];
transition.duration = 0.3f;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionReveal;
[self.navigationController.view.layer addAnimation:transition forKey:nil];
[self.navigationController pushViewController:phoneServicesViewController animated:NO];

Answer 5

不，从右到左保留用于从导航堆栈中弹出viewcontrollers。但是，您可以通过自己设置动画来获得此类效果。类似的东西：

[UIView beginAnimations:@"rightToLeft" context:NULL];
CGRect newFrame = aView.frame;
newFrame.origin.x -= newFrame.size.width;
aView.frame = newFrame;
[UIView commitAnimations];

但是这对导航控制器没有任何作用。

Answer 6

你似乎想“回弹”。这可以通过UINavigationController实例上的三种方法来实现：

回到“根”控制器：

-(NSArray *)popToRootViewControllerAnimated:(BOOL)animated

或者回到以前的控制器之一：

-(NSArray *)popToViewController:(UIViewController *)viewController animated:(BOOL)animated

或者回到之前推出的控制器：

-(UIViewController *)popViewControllerAnimated:(BOOL)animated

Answer 7

在我看来，这是对最佳答案的改进：

UIViewController *newVC = ...;
[self.navigationController setViewControllers:@[newVC, self] animated:NO];
[self.navigationController popViewControllerAnimated:YES];

要回到初始控制器，只需按一下即可。

Answer 8

基于@felixlam的回答，我升级并创建了一个“反向”方向导航控制器，它会覆盖默认的推/弹方法，就像这样。

class LeftPushNavigationController: BaseNavigationController {

  override func viewDidLoad() {
    super.viewDidLoad()
    interactivePopGestureRecognizer?.isEnabled = false
  }

  override func pushViewController(_ viewController: UIViewController, animated: Bool) {
    // If the push is not animated, simply pass to parent
    guard animated else { return super.pushViewController(viewController, animated: animated) }

    // Setup back button
    do {
      // Hide original back button
      viewController.navigationItem.setHidesBackButton(true, animated: false)
      // Add new one
      viewController.navigationItem.rightBarButtonItem = UIBarButtonItem(
        image: #imageLiteral(resourceName: "iconBackReverse"),
        style: .plain,
        target: self,
        action: #selector(self.pop)
      )
    }

    // Calculate final order
    let finalVCs = self.viewControllers + [viewController]

    // Insert the viewController to the before-last position (so it can be popped to)
    var viewControllers = self.viewControllers
    viewControllers.insert(viewController, at: viewControllers.count - 1)

    // Insert viewcontroller before the last one without animation
    super.setViewControllers(viewControllers, animated: false)
    // Pop with the animation
    super.popViewController(animated: animated)
    // Set the right order without animation
    super.setViewControllers(finalVCs, animated: false)
  }

  override func popViewController(animated: Bool) -> UIViewController? {
    // If the push is not animated, simply pass to parent
    guard animated else { return super.popViewController(animated: animated) }

    guard self.viewControllers.count > 1 else { return nil }

    // Calculate final order
    var finalVCs = self.viewControllers
    let viewController = finalVCs.removeLast()

    // Remove the parent ViewController (so it can be pushed)
    var viewControllers = self.viewControllers
    let parentVC = viewControllers.remove(at: viewControllers.count - 2)

    // Set the viewcontrollers without the parent & without animation
    super.setViewControllers(viewControllers, animated: false)
    // Create push animation with the parent
    super.pushViewController(parentVC, animated: animated)
    // Set the right final order without animation
    super.setViewControllers(finalVCs, animated: false)

    // Return removed viewController
    return viewController
  }

  @objc
  private func pop() {
    _ = popViewController(animated: true)
  }

}

Answer 9

我有同样的问题，这就是我解决的问题

[self.navigationController popViewControllerAnimated：YES];

这将类似于＆＃34;返回＆＃34;即单击后退按钮并导航到上一页的情况

Answer 10

Swift 4.2

 let pageView = TaskFolderListViewController.init(nibName: "HomePageController_iPhone", bundle: nil)
 let transition = CATransition()
 transition.duration = 0.45
 transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.default)
 transition.type = CATransitionType.push
 transition.subtype = CATransitionSubtype.fromLeft
 self.navigationController?.view.layer.add(transition, forKey: kCATransition)
 self.navigationController?.pushViewController(pageView, animated: false)

Answer 11

根据先前的最佳答案，您可以进行UINavigationController扩展并按以下方式保留导航堆栈：

extension UINavigationController {
    /// Pushes view controller into navigation stack with backwards animation.
    func pushBackwards(viewController newViewController: UIViewController) {
        if let currentController = viewControllers.last {
            let previousControllers = viewControllers[0..<viewControllers.endIndex-1]
            var controllers = Array(previousControllers + [newViewController, currentController])
            setViewControllers(controllers, animated: false)
            popViewController(animated: true)
            // Adjusting the navigation stack
            _ = controllers.popLast()
            controllers.insert(currentController, at: controllers.count-1)
            setViewControllers(controllers, animated: false)
        } else {
            // If there is no root view controller, set current one without animation.
            setViewControllers([newViewController], animated: false)
        }
    }
}

使用UINavigationController从右向左推送ViewController
