推荐答案

最简单的方法是在删除帧之前使用帧和alpha。

The easiest is playing with frame and alpha before removing it.

你可以得到一些很酷的效果

You can get some cool effects

-(void)removeWithEffect:(UIView *)myView
{
 [UIView beginAnimations:@"removeWithEffect" context:nil];
 [UIView setAnimationDuration:0.5f];
 //Change frame parameters, you have to adjust
 myView.frame = CGRectMake(0,0,320,480);
 myView.alpha = 0.0f;
 [UIView commitAnimations];
 [myView performSelector:@selector(removeFromSuperview) withObject:nil afterDelay:0.5f];
}

iOS更新

您现在可以使用块来执行动画

You can now use blocks to perform your animation

[UIView animateWithDuration:0.5f
     animations:^{view.alpha = 0.0;}
     completion:^(BOOL finished){ [view removeFromSuperview]; }];
