Objective-c – Completely close an OS X application with window close button

macosobjective cxcode

I need completely close my application when a user closes the document window using the applications at runtime.

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:

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 NSApp delegate implement applicationShouldTerminateAfterLastWindowClosed::

- (BOOL) applicationShouldTerminateAfterLastWindowClosed:(NSApplication *)application
{
    return YES;
}

Using Swift, it would be:

func applicationShouldTerminateAfterLastWindowClosed(_ sender: NSApplication) -> Bool {
     return true
}

Per Apple's Human Interface Guidelines (a guide for Mac developers):

In most cases, applications that are not document-based should quit when the main window is closed. For Example, System Preferences quits if the user closes the window. If an application continues to perform some function when the main window is closed, however, it may be appropriate to leave it running when the main window is closed. For example, iTunes continues to play when the user closes the main window.

Objective-c – Minimum window size of a Mac OS X application

Use -[NSWindow setMinSize:] to set the minimum size programmatically, but you can also set the minimum size inside Interface Builder (look at the tab with the sizes).

To make the application quit when the window is closed, you need to add this to your app delegate:

- (BOOL)applicationShouldTerminateAfterLastWindowClosed:(NSApplication *)theApplication
{
    return YES;
}
