NSFetchedResultsController delegate methods won't be called after rearranging table rows

Question

hi all

i wonder why the delegate methods of NSFetchedResultsController won't be called after i reorder table rows.

my problem is that rows disappear when i rearrange them in my tableview with the method - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath so i try to use the methods from the NSFetchedResultsController to fix that.

any suggestion?

thanks in advance!
