applicationDidChangeScreenParameters 和 [NSWindow orderOut:]
在我的应用程序中，应用程序的窗口必须在系统更改分辨率时关闭。虽然实现 - (void)applicationDidChangeScreenParameters:(NSNotification *)notification 很容易，但我遇到了一个奇怪的错误。
奇怪的是，当此通知触发时，我的窗口似乎无法响应 orderOut: 调用。它正在触发，因为我的 NSLog 工作正常，我什至尝试放入 [NSApp Terminate:nil] ，这也工作正常。当命令窗口退出时，还有其他不相关的方法并且它们工作没有问题，这就是奇怪的地方。
在这种情况下我的窗口无法关闭是否有原因？什么可能导致这种情况？
In my application, it's necessary that the application's window close upon the system changing resolutions. While it's easy enough to implement - (void)applicationDidChangeScreenParameters:(NSNotification *)notification, I've run into an odd bug.
Strangely, my window seems unable to respond to orderOut: calls when this notification fires. It IS firing, because my NSLog works fine and I even tried dropping in [NSApp terminate:nil], which also works fine. There are other unrelated methods when that order the window out and they work without problems which is what makes it strange.
Is there are reason that my window is unable to close in these circumstances? What could cause this?

您可以将关闭延迟到下一次运行事件循环吗？为此，请使用延迟为零的
-performSelector:withObject:afterDelay:。Can you just delay the close until the next run through the event loop? To do this, use
‑performSelector:withObject:afterDelay:with a delay of zero.
