title: UIViewController title is always (null)
body: <p>I have this problem. In my initial UIViewController, the title is always null. I have tried <code>[self setTitile:]</code> and many other ways of setting title, but nothing works. I suppose there should be the app name as title, and it should be set somewhere in Xcode maybe?

  <p>Here is how I set the title:</p>
  
  <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];
      [self.navigationItem setTitle:@"Your Title"];
      //[self setTitle:@"Some title"];
  
  . . . 
  }
  </code></pre>
  
  <p>I also set title in Storyboard, for the controller and the Nav controller that embeds it, but no luck.
  Thank you.</p>
