如何在Windows关闭时退出cocoa应用程序？

- (IBAction)closeButtonClicked:(id)sender {
    [NSApp terminate:nil];
}

- (void)applicationWillTerminate:(NSNotification *)notification {
    [NSApp terminate:nil];
}

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
    // 添加对NSApplicationWillTerminateNotification通知的监听
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(applicationWillTerminate:)
                                                 name:NSApplicationWillTerminateNotification
                                               object:nil];
}
