objective-c - CATransition如何运作？

我有两个 View ，一个是aView，另一个是bView，aView上有一个按钮，我单击该按钮，我将跳到bView，请查看代码

-(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，它会跳，所以我该怎么办？

最佳答案

您忘了实际上在最后添加 View ...

-(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];
}

有没有理由不使用UIView动画块？自iOS 4以来，这是动画的推荐方法。使用UIView的transitionFromView:toView:duration:options:completion:应该适合您...

[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，但是您可以选择任何UIViewAnimationOption。
