title: Set root controller with interface builder
body: <p>When I drag a Navigation Controller on to the storyboard I get the Navigation Controller and a  Table View Controller. I do not want the table view, so I delete it, insert a regular view controller, change its class to e.g LoginView, right-click and drag: "Relationship Root View Controller" from the Navigation Controller on to the View Controller. </p>
  
  <p>Now when I run the application I get </p>
  
  <pre><code>Application windows are expected to have a root view controller at the end of application launch
  </code></pre>
  
  <p>I do not want to fix this programatically, since last time I did this it worked out of the box (xcode 4.2, now I upgraded to 4.3). Also, when adding the Navigation Controller in 4.2 it came with a View Controller, not a Table View Controller. </p>
  
  <p>Navigation Controller has "Is Initial View Controller" set. </p>
