Question

ios中uiimageview中startAnimating有回调函数吗

Answer 1

没有，但你可以开一个NSTimer来监听UIImageView 的isAnimating属性的状态。根据这个来判断，伪代码如下：
[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(onTimer) userInfo:nil repeats:YES];

-(void)OnTimer {
if ( [imageView isAnimating] )
{
// still animating
}
else
{
// Animating done
}

}
