第一种方法:，使用监听

UIView beginAnimations

    [UIView beginAnimations:nil context:nil];
    //代理，监听对象
    [UIView setAnimationDelegate:self];

    //<span style="font-family: Arial, Helvetica, sans-serif;">removeCover 是动画执行完后要调用方法</span>
    [UIView setAnimationDidStopSelector:@selector(removeCover)];
    self.coverBtn.alpha =0.0;
    [UIView commitAnimations];

-(void)removeCover
{
    [self.coverBtn removeFromSuperview];
    self.coverBtn=nil;
}

    [UIView animateWithDuration:1.0 animations:^{
        self.coverBtn.alpha= 0.0;
        self.iconbtn.frame = self.oldPicFrame;
        
    } completion:^(BOOL finished) {
        [self.coverBtn removeFromSuperview];
        self.coverBtn =nil;
    }];
