If you're using an NSFetchedResultsController like me and updating data in a background thread, don't forget to begin and end updates in the delegate:

- (void)controllerWillChangeContent:(NSFetchedResultsController *)controller {
    [self.tableView beginUpdates];
}

- (void)controllerDidChangeContent:(NSFetchedResultsController *)controller {
    [self.tableView endUpdates];
}
