title: UINavigationController how to set title
body: <p>I have a Controller/View for a generic list of items, that can be extended for displaying a custom list.. Listing and navigation works fine.. but I can't change the title of UINavigationController.
  In the generic Controller:</p>
  
  <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];
      [self.view addSubview: navigationController.view];
  }
  - (void)setNavigationTitle: (NSString *)title
  {
      NSLog(@"set title: %@", title); // this works
      self.navigationController.title = title; // Nothing works here
  }
  </code></pre>
  
  <p>Then, the extended class does..</p>
  
  <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];
      [self setNavigationTitle: @"Custom list"];
  }
  </code></pre>
  
  <p>The navigationBar still have "Item" as title :(</p>
