title: How do I call a custom init on a view controller instantiated from a Storyboard scene in interface builder?
body: <p>If I am using interface builder to manage storyboards for my app, how can I call a custom <code>init</code> selector when view / view controller instances are created?</p>
  
  <p>For example if  I have a view controller in a Storyboard scene, and its <strong>Custom Class</strong> is a <code>UIViewController</code> subclass, with a custom initialiser, such as <code>initWithMediaType:</code>, which takes an <code>NSUInteger</code> as an argument, how can I specify in Interface Builder that <code>initWithMediaType:</code>should be called, passing in a given argument?</p>
