I have been working on an RSS reader app for quite some time, and I want to implement it as a part of another app already developed. I have the RootViewController.h,m,xib DetailView.h,m,xib all copied to the tab bar app. In IB I go to the tab I would like the Blog and RootViewController to appear and change the Class Identity to RootViewController, but when I compile the app, it stays the same. Am I going about this the wrong way?
