推荐答案

试图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.(你还记得退出苹果事件吗?)

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?)

实施 应用程序委托中的 applicationShouldTerminate: 方法.竖起密码面板，返回NSTerminateLater.然后，当用户输入正确的密码或取消时，发送应用程序 a replyToApplicationShouldTerminate: 消息.

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.

无论您已经删除了哪些退出命令(菜单项等)，请将它们放回去.让用户以正常方式调用正常的 Quit 命令；这将触发上述应该终止的程序，以确定是否真的会发生戒烟.

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.
