title: Passing an NSManagedObjectContext to a tableview when its embedded in navigation controller
body: <p>I'm creating an application with a few TableViews and i have the first screen which is a normal view, im creating in the AppDelegate a <code>NSManagedObjectContext</code> and I was passing it to other views using this for example:</p>
  
  <pre><code>PickTypeViewController *controller = (PickTypeViewController *)segue.destinationViewController;
  controller.managedObjectContext = self.managedObjectContext;
  </code></pre>
  
  <p>But now I embedded my tableview in a navigation controller (Editor-emmbed in -navigation controller) and I want to transfer the <code>NSManagedObjectContext</code> to my tableview but I dont know how to send it through the navigation controller.</p>
