title: Hide Navigation Controller Back Button iOS 7
body: <p>I have tried to hide the back button in my navigation controller by adding the following lines to my <code>viewDidLoad</code> method. Many other previous answers on SO have said this works, so I don't know what my problem is? Maybe something new with iOS 7 / Xcode 5?</p>
  
  <pre><code>self.navigationItem.hidesBackButton = YES;
  self.navigationController.navigationItem.hidesBackButton = YES;
  </code></pre>
