如果你只想使用 CATransition

CATransition *animation = [CATransition animation];
[animation setType:kCATransitionMoveIn];
[animation setSubtype:kCATransitionFromTop];
[animation setDuration:0.6f];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:
                              kCAMediaTimingFunctionEaseInEaseOut]];
[subview.layer addAnimation:animation forKey:@"someTransition"];
