  <p>I need empty back button title, so using category method as:</p>
  
  <pre><code>-(void)removeBackButtonTitle
  {
      UIBarButtonItem *newBackButton =
      [[UIBarButtonItem alloc] initWithTitle:@""
                                       style:UIBarButtonItemStylePlain
                                      target:nil
                                      action:nil];
      [[self navigationItem] setBackBarButtonItem:newBackButton];
  }
  </code></pre>
  
  <p>But I have a situation where I need to take <code>Container View</code> and some viewcontroller as child view controller and its view as a subview. Now upon navigation from this view, back button title is not setting to empty.</p>
