When I make a sample app (ie, start out with a tab bar application or something), in my MainWindow.xib file, I see 5 items listed -- File's Owner, First Responder, App Delegate, Window, and Tab Bar Controller.

If I make another .xib file, and make a delegate for it, and set that File's Owner to my new delegate that I just made, I do NOT see "NewDelegateFile" in the list of...objects(?) for that .xib.

This doesn't make sense to me, and I think is a huge part of why I'm not catching on all that quickly to iPhone development.

Does anyone care to take the time to explain that little peculiarity to me?
