【问题描述】：

我正在使用以下代码将 UIViewController 推送到导航堆栈中

[UIView animateWithDuration:0.75
                     animations:^{
                         [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
                         [self.navigationController pushViewController:ViewController animated:NO];
                         [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
                     }];

现在，当我按下返回时，我希望它执行相同的动画，但它不起作用。知道为什么吗？

在 ViewController.m 中

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

你把代码放在 ViewController.m 的什么地方？

其实过渡应该是这样的

//主视图

[UIView transitionWithView:self.navigationController.view
                      duration:0.75
                       options:UIViewAnimationOptionTransitionFlipFromRight
                    animations:^{
                        [self.navigationController pushViewController:viewcontroller animated:NO];
                    }
                    completion:nil];

//在视图控制器中

[UIView transitionWithView:self.navigationController.view
                  duration:0.75
                   options:UIViewAnimationOptionTransitionFlipFromLeft
                animations:^{
                    [self.navigationController popToRootViewControllerAnimated:NO];
                }
                completion:nil];

【讨论】：

你能告诉我为什么 self.view 不工作而不是 self.navigationController.view
@SuryaKantSharma 一般的想法是 NavigationController 拥有一个 viewController 数组。在视图级别内部，navigationController.view 将持有 viewcontroller.view，并且 push/pop 转换在 navigationController.view 上完成。所以 navigationController.view 应该是过渡视图。

【解决方案2】：

//FirstViewController
[UIView beginAnimations:@"animation" context:nil];
[UIView setAnimationDuration:0.8]; 
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];
[self.navigationController pushViewController: viewcontroller
 animated:NO];
[UIView commitAnimations];

//SecondViewController
[UIView beginAnimations:@"animation" context:nil];
[UIView setAnimationDuration:0.8];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO]; 
[self.navigationController popViewControllerAnimated:NO];
[UIView commitAnimations];

【解决方案3】：

在 Swift 4 中：

推送：

UIView.transition(with: (self.navigationController?.view)!, duration: 0.75, options: .transitionFlipFromRight, animations: {
            self.navigationController?.popViewController(animated: true)
        })

流行：

  UIView.transition(with: (self.navigationController?.view)!, duration: 0.75, options: .transitionFlipFromLeft, animations: {
            self.navigationController?.popViewController(animated: true)
        })
