如何等待动画师完成？ [英] How to wait for an animator to finish?

问题描述

这可能是一个简单的问题，但我似乎不知道如何做。基本上我想做的就是在关闭之前淡入一个窗口：

This is probably a simple question but I can't seem to figure out how to do it. Basically all I want to do is fade a window before closing it:

[[window animator] setAlphaValue:0.0];
[window close];

这个工作正常，没有[窗口关闭]，但当包括窗口似乎关闭它在动画结束之前（这显然不是我想要的）;对于orderOut :, performClose：等同样的情况也是如此。有没有办法避免这种情况？

This works fine without the [window close], but when that is included the window seems to close it before the animation finishes (which is obviously not what I want); the same seems to happen for orderOut:, performClose:, etc. Is there any way to avoid this?

推荐答案

[[window animator] setAlphaValue:0.0];
[window performSelector:@selector(performClose:) withObject:self afterDelay:[[NSAnimationContext currentContext] duration]];
