title: Properly set the view Outlet for a navigation Controller embedded in a tabBar Controller
body: <p>I am making an application which implements the following structure :</p>
  
  <pre><code>MainWindow
    |_ tabBar Controller
          |_ FirstView 
          |_ SecondView 
          |_ ThirdView 
          |_ FourthView 
                |_ navigation Controller
                      |_ ViewA
                      |_ ViewB
  </code></pre>
  
  <p>Following a tutorial, I have the tabBar controller and switch between views (1, 2, 3) working properly, the code I need is executed for each display of those views 1, 2, 3.</p>
  
  <p>Now I want to make it more complex and load a view that is just a Navigation Controller, becasuse my 4th item content is like a Blog (List of articles, when you click on one, it will show the summary)</p>
  
  <p>The code for the navigation controller and 2 views works well in a separate project where the navigation Controller is in the MainWindow nib. Now that I want to move it in the FourthView, I have the following error on execution :</p>
  
  <pre><code>2010-10-03 00:26:45.248 Scaning[1037:307] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "FourthView" nib but the view outlet was not set.'
  </code></pre>
  
  <p>I understand this is a problem in Interface Builder where I need to associate a view outlet, but I am new at iPhone development and can't figure out why the behaviour is different if the navigation Controller is not on the main window.</p>
  
  <p>Do you know any sample app that implements both tabbar controller and navigation controllers that I could analyze? Otherwise, any advice for that?</p>
  
  <p>Thanks !</p>
