title: Hiding Three20 Navigation Bar Back Item
body: <p>I am sort of newbie in Three20 world, and I am trying to hide the back/left button in navigation bar. </p>
  
  <p>Below is the method I am calling to hide it:</p>
  
  <pre><code>[[TTNavigator navigator].topViewController.navigationController.navigationItem setLeftBarButtonItem:nil animated:YES];
  
  [[TTNavigator navigator].topViewController.navigationController.navigationItem setHidesBackButton:YES animated:YES];
  </code></pre>
  
  <p>Apparently, both the methods doesn't hide the back button. What I am here trying to do is, push the viewcontroller, and when the new controller arrives it doesn't show the back button, yet I had another button there which pop's the view.</p>
  
  <p>I have also tried different routes as:</p>
  
  <pre><code>[VC.navigationController.navigationItem setHidesBackButton:Yes];
  </code></pre>
  
  <p>The funny part is I am about to set the Title though as:</p>
  
  <pre><code>[VC.navigationItem setTitle:@"Options"];
  </code></pre>
  
  <p>Any help here will be really appreciated. Thanks.</p>
