### 为什么UIView动画结束函数被调用了两次??
[UIView beginAnimations:@"fadeOut" context:nil];
[UIView setAnimationDuration:5.0];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(animationStopped)];
self.alpha = 0.0;
[UIView commitAnimations];
animationStopped一开始就被调用了,然后5秒后又被调用一次??
[解决办法]
你设置了委托就别再手动添加一个委托了,[UIView setAnimationDidStopSelector:@selector(animationStopped)];这句不要。找找动画停止的委托。
或者不要这句[UIView setAnimationDelegate:self];
