title: tabBarController and first Tab viewDidLoad
body: <p>I have created a tabBarNavigated Application. In second tab, I do something that works fine, but now I want to do something in the first Tab, so first I try to <code>NSLog</code> a string, but I get no reaction. </p>
  
  <pre><code>- (void)viewDidLoad
  {
   NSLog(@"Test");
  }
  </code></pre>
  
  <p>If I add a label to the view, it will be displayed, but no reaction on my code.</p>
  
  <p>if I start my app, i see this view, but i can't call any actions in this method, even if i change the tab, and go back to the first one, still no logs.</p>
