推荐答案

尝试拦截用户可能告诉您的应用程序退出的所有可能方式，注定会失败. (您还记得退出苹果活动吗?)

Trying to intercept all possible ways the user might tell your application to quit is bound to fail. (Did you remember the Quit Apple Event?)

仅实现

It'll be both easier and more effective to just implement the applicationShouldTerminate: method in your application's delegate. Put up the password panel and return NSTerminateLater. Then, when the user either enters the correct password or cancels, send the application a replyToApplicationShouldTerminate: message.

退出已经退出的命令(菜单项等)，然后放回去.让用户以常规方式调用常规的Quit命令；这将触发上述应该终止的过程，以确定退出是否会真正发生.

Whichever Quit commands (menu items, etc.) you've already ripped out, put them back. Let the user invoke the normal Quit command in the normal way; that will trigger the aforementioned should-terminate procedure to determine whether the quit will actually happen.
