Re: NSApplication callback of some sort?

Basically you do two things. First you set your object as NSApp's delegate:

[NSApp setDelegate:self];

Do this somewhere in your object's initialization. Then you implement the delegate method(s) you want to use.

- (void)applicationWillTerminate:(NSNotification *)aNotification
{
//do stuff
}

Just add this method in your object class's implementation and insert the code you want executed when this method is called. Some delegate methods have return types which will allow you some control over NSApp.

- (NSApplicationTerminateReply)applicationShouldTerminate:(NSApplication *)sender
{
if(someCondition)
return NSTerminateCancel;
else
return NSTerminateNow;
}

This will allow you to stop the application from quitting.

Ok, are there any examples on Apple's site or the Developer examples that illustrate using NSApplication delegates? I am really new to this and haven't used them yet (obviously) :)
