title: Terminating app due to uncaught exception, while loading a view
body: <p>I am getting this error, while I am trying to load another view</p>

  <p>Here new1 is a button, which when pressed loads a view.</p>
  
  <p>And here is the code inside the new1</p>
  
  <pre><code>-(IBAction) new1:(id) sender
  {
   viewController = [[iTViewController alloc] initWithNibName:@"iTViewController" bundle:[NSBundle mainBundle]];
      [self.view addSubview:viewController.view];
  }
  </code></pre>
  
  <p><strong>Note: When I launch the App from fresh and press the new1 button, it works flawlessly, but when I press other button which loads other view and when I return back to this view and press new1, then it crashes</strong></p>
