提问by DevCompany
I need completely close my application when a user closes the document window using the applications at runtime.
当用户在运行时使用应用程序关闭文档窗口时，我需要完全关闭我的应用程序。
Currently when they click the window, the application stays open and is displaying its menu bar. I read this article for iOS and to add an entry into the plist file: http://developer.appcelerator.com/question/40081/ios4---make-app-not-run-in-background
当前，当他们单击窗口时，应用程序保持打开状态并显示其菜单栏。我为 iOS 阅读了这篇文章，并在 plist 文件中添加了一个条目：http: //developer.appcelerator.com/question/40081/ios4---make-app-not-run-in-background
What is the easiest way for me to close the entire app when a user closes the document window?

Is this a Mac app? If so, have your NSAppdelegate implement applicationShouldTerminateAfterLastWindowClosed::
这是 Mac 应用程序吗？如果是这样，请让您的NSApp委托实施applicationShouldTerminateAfterLastWindowClosed:：
- (BOOL) applicationShouldTerminateAfterLastWindowClosed:(NSApplication *)application
{
return YES;
}
Using Swift, it would be:
使用 Swift，它将是：
func applicationShouldTerminateAfterLastWindowClosed(_ sender: NSApplication) -> Bool {
return true
}

Add the NSWindowDelegatein YourWindowController.hfile and then add the following method in YourWindowController.mfile:
添加NSWindowDelegateinYourWindowController.h文件，然后在文件中添加以下方法YourWindowController.m：
-(void)windowWillClose:(NSNotification *)notification
{
// You can use either of the following lines:
[[NSApplication sharedApplication] terminate:nil];
// OR
exit(0);
}
You will need to use the NSWindowDelegate for all your windows.
您将需要为所有窗口使用 NSWindowDelegate。
