在自定义过渡中闪烁，ios7

Question

我使用以下代码：

    CATransition *transition = [[CATransition alloc]init];
    transition.duration = 0.3;
    transition.type = kCATransitionMoveIn;
    transition.subtype= kCATransitionFromLeft;
    //transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
    [self.navigationController.view.layer addAnimation:transition forKey:kCATransactionCompletionBlock];

并在视图右侧获得视觉闪烁。如果我使用kCATransitionFromRight，我会在左边眨眼。我在模拟器和设备上进行了测试。这是不对的？

Answer 1

使用波纹管代码并按照波纹管说明进行操作

  CATransition *navTransition = [CATransition animation];
    navTransition.duration = 0.65;
    navTransition.timingFunction = [CAMediaTimingFunction 
          functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    [navTransition setType:kCATransitionReveal];
    [navTransition setSubtype:kCATransitionFromRight];
    [view.navigationController.navigationBar.layer 
          addAnimation:navTransition forKey:nil];

这是一个最好的方法：

为您的UINavigationController创建UINavigationControllerDelegate。您将听到通过委托方法之一（如 navigationController:willShowViewController:animated:）将新视图推送/弹出到导航堆栈的信息。在适当的委托方法中，您可以在自定义UIViewController上设置属性，以便它知道要在viewWillAppear等中使用哪个动画。

如果部署目标是 7.0，请使用 UINavigationControllerDelegate 自定义推送/弹出动画。

它有点复杂，但它非常强大。无论你想象什么，你都可以用这些代表来做。

- (id <UIViewControllerInteractiveTransitioning>)navigationController:(UINavigationController *)navigationController
                      interactionControllerForAnimationController:(id <UIViewControllerAnimatedTransitioning>) animationController NS_AVAILABLE_IOS(7_0);
- (id <UIViewControllerAnimatedTransitioning>)navigationController:(UINavigationController *)navigationController
                               animationControllerForOperation:(UINavigationControllerOperation)operation
                                            fromViewController:(UIViewController *)fromVC
                                              toViewController:(UIViewController *)toVC  NS_AVAILABLE_IOS(7_0);
