cocoa release nswindowcontroller

I am loading a window with it's controller from a window nib file. The window has a "release when closed" option enabled. How could i开发者_Go百科 release the controller as soon as the window closes?

Thank you

In your windowWillClose: code don't forget that you'll need to removeObserver: or your controller will never be released because the NSNotificationCenter has retained it.

In the window controller subscribe to window close notification.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(windowWillClose:) name:NSWindowWillCloseNotification object:window];

and in windowWillClose: method write code to release your window controller.
