title: UINavigationBar appearance override in iOS 5
body: <p>I have had the following code:</p>
  
  <pre><code>[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navbarBackBlack.png"] forBarMetrics:UIBarMetricsDefault];
      [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navbarBackBlack.png"] forBarMetrics:UIBarMetricsLandscapePhone];
      [[UINavigationBar appearance] setTintColor:[UIColor colorWithWhite:0.72 alpha:1.0]];
  </code></pre>
  
  <p>But now I want to have one place in my app where I want the navbar to be a different color than this universal color I've set throughout the app. How can I change this for this particular settings only. Is it possible?</p>
