是否有像“willShowWindow”这样的 NSWindow 通知/委托方法？
我似乎无法在文档中找到它，但我正在寻找一种方法来运行一个方法，每当我的应用程序启动后或关闭然后重新打开后屏幕上显示一个窗口时。
I cannot seem to find it in the documentation but I'm looking for a way to run a method whenever a window is displayed on screen after launch of my app or after it has been closed and then reopened again.

您可以尝试使用
NSWindowDidBecomeKeyNotification或NSWindowDidBecomeMainNotification。当窗口成为关键/主窗口时而不是在屏幕上显示时，将调用这些窗口，但大多数窗口在进入屏幕时都会成为关键/主窗口。您还可以尝试其他 NSWindow 通知（请参阅 NSWindow 文档页面的底部），当窗口出现在屏幕上时，可能会调用其中一些通知。You could try using
NSWindowDidBecomeKeyNotificationorNSWindowDidBecomeMainNotification. These are called when the window becomes key/main rather than when it's put on-screen, but most windows are made key/main when they go on-screen. You could also experiment with the other NSWindow notifications (see the bottom of the documentation page for NSWindow), it's possible that some of them may be called when the window goes on-screen.NSWindowController：
– windowDidLoad
– 窗口将加载
NSWindowController:
– windowDidLoad
– windowWillLoad
