Would you care to elaborate on that? Your application should not invoke that method: NSApplication will invoke it automatically on it's delegate if it:
a) has a delegate
and
b) the delegate responds to that message.

It's a good idea to use [ code ] (without the spaces) tags around your code to prevent the insertion of 🙁
That method only gets called if the object that it is a member of is instantiated and set as the NSApplication delegate. Are you doing that (if so where). Personally I normally create an instance of my application delegate and connect it in MainMenu.nib.

The first question makes no sense. You do not connect "functions" (which are really called methods) to delegates
A delegate is simply an instance of an object. So you create a new class that implements the required methods.
You can then either create an instance of this object in your code and connect it to another object via the setDelegate: method, or you can instantiate this class in your nib and connect it there via the normal connection dragging method.
All of this is covered in any basic Cocoa introduction/tutorial.
I suggest you start reading
