我有一个名为UIView的以下CATransition finalScoreView,它使它从顶部进入屏幕:

CATransition *animation = [CATransition animation];
animation.duration = 0.2;
animation.type = kCATransitionPush;
animation.subtype = kCATransitionFromBottom;
animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];

[gameOver.layer addAnimation:animation forKey:@"changeTextTransition"];
[finalScoreView.layer addAnimation:animation forKey:@"changeTextTransition"];

如何使它在它下降后反弹一次然后保持静止？它应该仍然从顶部进入屏幕,但在它关闭时反弹.

任何帮助将不胜感激,谢谢!
