title: Create UINavigationController in UITableViewController inside UITabBarController
body: <p>I have an application with based of <strong>UITabBarController</strong>, and inside one of the tabs I have <strong>UITableViewController</strong> to display "products", till here everything is working perfectly.</p>
  
  <p>Now I want when clicking one of the cells inside the <strong>UITableViewController</strong> to open a <strong>UINavigationController</strong> to display <strong>UIViewController</strong> with details of that product.</p>
  
  <p>I think the application hierarchy should be like the following:</p>
  
  <pre><code>UITabBarController (BASE) Level-1
    |
    |___ UITableViewController (PRODUCTS) Level-2
           |
           |___ UINavigationController Level-3
                  |
                  |___ UIViewController (PRODUCT DETAILS) Level-4
  </code></pre>
  
  <p>How to achieve Level-3 and Level-4?</p>
  
  <p>Thanks in advance :)</p>
