让视图慢慢消失的效果

在调用 removeFromSuperview 的时候，当前视图会突然消失,这样显得很不友好。这段代码能够让视图慢慢消失。

使用 Core Animation 制作视图过渡动画

 

1 2 3 4 5 6 7 8 9 10 11

CATransition *animation = [ CATransition animation ]; animation .delegate = self ; animation .duration = 1 .0f ; animation .timingFunction = UIViewAnimationCurveEaseInOut ; animation .type = kCATransitionMoveIn; animation .subtype = kCATransitionFromTop;   // Perform some kind of view exchange or removal here, for example [myView exchangeSubviewAtIndex : 0 withSubviewAtIndex : 1 ];   [myView .layer addAnimation :animation forKey : @"move in" ];
