title: Setting ViewController's managedObjectContext
body: <p>I am using CoreData and I set the <code>NSManagedObjectContext</code> in <code>AppDelegate</code> file.</p>
  
  <p>I need to get that managedObjectContext in a ViewController which is many levels deep in the naviagation tree. Obviously, I do not want to pass it along all the init methods.</p>
  
  <p>I have tried <code>[[[UIApplication sharedApplication] delegate] managedObjectContext];</code> but I get this error "<strong>No known instance method for selector 'managedObjectContext'</strong>"</p>
  
  <p>Can someone guide me on how to get the managedObjectContext from <code>AppDelegate</code> to this <code>ViewContoller</code>?</p>
