title: Tableview is blank
body: <p>I have a tableview controller on my storyboard. I customized it in Xcode to have static cells and also added some cells to it. When running, my table is empty, I can not see my static cells.</p>
  
  <p>The main steps I did:</p>
  
  <ul>
  <li>added tableview controller to the storyboard</li>
  <li>added UITableViewController file</li>
  <li>set class of my tableview to my added tableviewcontroller class</li>
  <li>set content mode to static cells</li>
  <li>added some cells to the list</li>
  <li>implemented numberOfSectionsInTableView (return 1)</li>
  <li>implemented numberOfRowsInSection (return 5)</li>
  </ul>
  
  <p>I can see my tablewviewcontroller, but table is blank.</p>
  
  <p>Thanks in advance!</p>
