The detail label on each cell of my UITableViewCotroller gives the size of the folder it represents. The size may change, and whenever it does I need to change all of the detailLabels. One way would be to perform a reload, [tableview reloadData];, however the many images make it slow. Is there a way to just update the label?

I tried the method but I don't seem to be able to get it to work:

```
[tableView beginUpdates];
…
[tableView endUpdates]; 

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    cell.detailTextLabel.text = @"";
    return cell;
}

```
