title: Attach .m and .h files to a storyboard's TabBar Controller
body: <p>I've implemented a new part of my application made by .m .h and xib (yeah, it's old) with storyboard, in particular a view with a tabBar controller and 2 item linked to it. I instantiate the storyboard with:</p>
  
  <pre><code>NVPassportViewController *passportBookController = [[UIStoryboard storyboardWithName:@"NVPassportViewController" bundle:nil] instantiateViewControllerWithIdentifier:@"passportViewController"];
  </code></pre>
  
  <p>Now, I know that I can attach .m and .h files in the tabBar controller of the storyboard, setting "custom class" to <code>NVPassportViewController</code>, but the <code>viewDidLoad</code> method of  <code>NVPassportViewController</code> is never called with the tabBar of the storyboard on screen. Why? linking the tab1's and tab2's view to specific .m and .f files is working, but with main tabView controller no.</p>
  
  <p>EDIT: solved and i think that's a important know-how for custom class and storyboard: you can't name your Storyboard file and custom class with the same name.</p>
