NSApplication posts this notification to the default notification
center. NSApplication also automatically signs its delegate up for
this notification.
Kyle, from the "Cocoa Fundamentals Guide": "Although you can
dynamically change the delegate, only one object can be a delegate
at a time. Thus if you want multiple objects to be informed of a
particular program event at the same time, you cannot use
delegation."
So, if I understand you and the documentation correctly , even
though I had implemented the delegate of NSApplication in **both**
of my classes, **only** one of those classes will respond to
"applicationWillTerminate:" at a time. If this is indeed correct,
then I need to rethink the design of my application, and you have
already suggested how to do this.
True, only one object can be the application delegate at any one
time. However, multiple objects can be subscribed to application
notifications, and the notification will be sent to all subscribed
objects when it is posted.
Jason....I will re-read those, but your insight has clarified
something that was confusing. Much appreciated.
