Realtime Updates with the iOS SDK

To receive updates from the fetchController, be sure to implement the NSFetchedResultsControllerDelegate protocol methods:

(void)controllerDidChangeContent:(NSFetchedResultsController *)controller
(void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject
  atIndexPath:(NSIndexPath *)indexPath
  forChangeType:(NSFetchedResultsChangeType)type
  newIndexPath:(NSIndexPath *)newIndexPath
