I am following the CoreDataBooks Sample Code in a Utility Application, and so far, I have been able to display a tableView without the Navigation bar on top. How can I get the Naviagation bar to display at the top? The TableView is in the FlipsideViewController. I think that the problem is that the sample code has a MainWindow.xib that contains a navigation controller and a Utility Application does not. How can I create a MainWindow.xib and only have the Navigation Controller on the FlipsideViewController? Thanks!
