title: Is it possible to initialize a UINavigationController subclass from a NIB?
body: <p>I have a <code>UITabBarController</code> based application. The tabs will be created from database entries, so I don't know them in advance. I'd like to <strong>programmatically</strong> initialize a <code>UINavigationController</code> subclass (I have a few different kinds) for each tab. </p>
  
  <p>Ideally, I would really like to draw the whole <code>UINavigationController</code> subclass + it's subview using Interface Builder, just like you can do when you add define the view for each tab in IB (that's when you know what the tabs will be in advance). I've tried setting the "Class identity" to my <code>UINavigationController</code> subclass name, then add a <code>UINavigationController</code> inside it, but obviously it didn't inject the instance at the "File's owner" level...</p>
  
  <p>Thanks</p>
