如何为removeFromSuperview设置动画

Question

我通过以下方式为子视图的外观设置了动画:

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionReveal;
[webView.layer addAnimation:transition forKey:nil];

[self.view addSubview:webView];

但现在我想删除我的subView.如何添加动画来执行此操作？像其他CATransition一样？什么时候加？在addSubview之前或之后？

那么你可以先做动画和animationEndListener电话removeFromSuperView

[UIView animateWithDuration:0.5
    delay:1.0
    options: UIViewAnimationOptionCurveEaseOut
    animations:^{
        yourView.alpha = 0;
    }completion:^(BOOL finished){
        [yourView removeFromSuperview];
    }];
