title: Tab Bar Application With Navigation Controller
body: <p>I have a simple iPhone app that has a tab bar and 3 tabs. Each tab loads as a separate nib with a corresponding controller. Each nib contains a tableview with some other controls for searching/filtering etc.</p>
  
  <p>What I would like (and cant seem to find an example of) is adding a navigation controller to the app so each nib (i.e. each tab) can drill down to further detail pages.</p>
  
  <p>Should I be adding a navigation controller to the main window and creating an <code>IBOutlet</code> for it or should the NC be added to the nibs.</p>
