title: iOS >> UINavigation Item Back Button Title Doesn't Change
body: <p>I'm trying to set the BACK button for a pushed VC set within a UINavigationController stack. I use the following code, and it's not working - I still get the previous VC name appearing as the back button title.</p>
  
  <pre><code>-(void)viewWillAppear:(BOOL)animated {
  
      [super viewWillAppear:animated];
  
      self.title = @"VC Title";
  
      UIBarButtonItem* myBackButton = [[UIBarButtonItem alloc]
                                       initWithTitle:@"Back"
                                       style:UIBarButtonItemStyleBordered
                                       target:nil
                                       action:nil];
  
      self.navigationItem.backBarButtonItem = myBackButton;
  
  }
  </code></pre>
  
  <p>Anyone?</p>
