#1

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，在添加按钮时，所要做的就是控制从按钮拖拽到应用程序图标并连接方法terminate:。

#2

[[NSApplication sharedApplication] terminate:self];

#3

Try the following:

试试以下:

[NSApp terminate: nil];

#4

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，调用[NSApp terminate:self]时不能关闭app;就像当在doc窗口上显示NSAlert时一样(NSAlert -beginSheetModalForWindow:completionHandler:)……

You can close all window and alert before call terminate, like following code:

您可以关闭所有窗口和警报，在调用终止之前，像以下代码:

for (NSWindow *window in [NSApplication sharedApplication].windows) {
    [window close];
}
[NSApp terminate:self];
