问题描述

我不知道为什么它是如此困难，但是基本上我想在整个屏幕上制作一个NSView动画，一旦完成该动画，就删除该NSView.但是，似乎我找不到有关如何执行此操作的参考.有人可以帮忙吗?

I do not know why it is proving to be so difficult, but basically I want to animate an NSView across my screen, and once it is done that animation, remove that NSView. It however seems that I can find absolutely no reference on how to do this. Can someone please help?

我要像这样开始动画

NSRect frame = blob.frame;
frame.origin.x = animationStopX;
[NSAnimationContext beginGrouping];
[[NSAnimationContext currentContext] setDuration:timeToDisappear];
[[blob animator] setFrame:frame];
[NSAnimationContext endGrouping];

一旦完成，我将无法从中获得回调.

I have no way of getting a callback from this once it completes or anything.

推荐答案

在beginGrouping语句之后，添加以下内容:

Right after your beginGrouping statement, add this:

[[NSAnimationContext currentContext] setCompletionHandler:^{
        [self.blob removeFromSuperview];
    }];

setCompletionHandler:是NSAnimationContext类中的方法.
