title: View controller with a navigation controller
body: <p>Can you point me a guide/tutorial/sample how to implement this correctly?</p>
  
  <p>I just want in the first view (it's a view controller) there's a button.
  Clicking the button will go to the 2nd view. The 2nd view will have a navigation controller and a table view (the table view will drill down to the 3rd view).</p>
  
  <p>Most tutorial I've found, they added the navigation controller to the main window and the root view controller is called from navigation controller.. but what if it's the other way around just like my case? Is it possible? how?</p>
  
  <p>Thanks</p>
