I'd like to add that if you are using multiple NSFetchedResultsControllers for the same entity, but in different tables, your UITableView will not update if you insert data for the same entity using another controller. This is because your UITableView will not receive willChangeContent ,etc messages from an NSFetchedResultsController for which you have not set yourself as a delegate.
