//动画效果

[UIView beginAnimation:nil context:nil];

[UIView setAnimationDelegate:self];

[UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];

[UIView commitAnimations];

//动画结束时的释放动作

-(void) animationDidStop:(NSString*)animationID finished:(NSNumber*)finished context:(void*)context

{

[subView removeFromSuperView];

[subView release];

subView=nil;

}
