我有两个视图，一个是aView，另一个是bView，aView上有一个按钮，我点击按钮，我会跳转到bView，请看代码

-(IBAction)jump2b:(id)sender{
CATransition *animation = [CATransition animation];
animation.delegate = self;
animation.duration = 0.25f;
animation.timingFunction = UIViewAnimationCurveEaseInOut;
animation.fillMode = kCAFillModeForwards;
animation.removedOnCompletion = NO;
animation.type = kCATransitionPush;
animation.subtype = kCATransitionFromTop;
   [bView.view.layer addAnimation:animation forKey:@"animation"];
 }

它不能很好地工作，它可以跳，那我该怎么办？谢谢

你忘了在最后添加视图......

-(IBAction)jump2b:(id)sender{
    CATransition *animation = [CATransition animation];
    animation.delegate = self;
    animation.duration = 0.25f;
    animation.timingFunction = UIViewAnimationCurveEaseInOut;
    animation.fillMode = kCAFillModeForwards;
    animation.removedOnCompletion = NO;
    animation.type = kCATransitionPush;
    animation.subtype = kCATransitionFromTop;
    [bView.view.layer addAnimation:animation forKey:@"animation"];

    //add bView to current view
    [self.view addSubview:bView];
}

您是否有理由不使用 UIView 动画块？这是自 iOS 4 以来推荐的动画方法。使用 UIView 的 transitionFromView:toView:duration:options:completion: 应该适合你...

[UIView transitionFromView:aView 
                    toView:bView 
                  duration:0.25 
                   options: (UIViewAnimationCurveEaseInOut | UIViewAnimationOptionTransitionCurlUp)
                completion:nil];

我使用 UIViewAnimationOptionTransitionCurlUp 作为过渡选项的示例，但您可以选择任何 UIViewAnimationOption。
