There is a simpler form to quit from code:
有一种更简单的形式可以退出代码：
[NSApp terminate:self];
But as you're adding a button, all you have to do is to control drag from your button to the Application icon and connect the method terminate:.
但是当您添加按钮时，您所要做的就是控制从按钮到应用程序图标的拖动并连接方法terminate:。

In some case you cannot close app when call [NSApp terminate:self];. Like when showing NSAlert as sheet on the doc window (NSAlert -beginSheetModalForWindow:completionHandler:) ...
在某些情况下，您无法在调用时关闭应用程序[NSApp terminate:self];。就像在文档窗口 ( NSAlert -beginSheetModalForWindow:completionHandler:)上将 NSAlert 显示为工作表一样......
You can close all window and alert before call terminate, like following code:
您可以在呼叫终止之前关闭所有窗口和警报，如下代码所示：
for (NSWindow *window in [NSApplication sharedApplication].windows) {
[window close];
}
[NSApp terminate:self];
