Empty UITableView

Question

I have a editable tableView and i cant remove the last object heres my method :

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView beginUpdates];
    if (editingStyle == UITableViewCellEditingStyleDelete)
    {
        [self deletePermittedFriend:[friendsIDs objectAtIndex:indexPath.row]];
        [tableDataList removeObjectAtIndex:indexPath.row];
    }

    [tableView endUpdates];
}

and if the tableDataList MutableArray have only one last object gives me an error :

* Assertion failure in -[UITableView _endCellAnimationsWithContext:], /SourceCache/UIKit/UIKit-2380.17/UITableView.m:1070 2013-05-21 11:41:47.306 EzMall[3398:907] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (0) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (0 inserted, 0 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).'

Answer 1

It looks that you forgot to call this UITableView method:

– deleteRowsAtIndexPaths:withRowAnimation:

BTW: It is always good practice to read error messages.

Answer 2

Try this

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
    {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [tableDataList removeObjectAtIndex:indexPath.row];

        [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }


    [self.tableView beginUpdates];
    [self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationAutomatic];
    [self.tableView endUpdates];
    }
