iPhone: Modify a cell selected in didSelectRowAtIndexPath

Question

I have a table with entries which the user can select and when clicking on them the UILabel should turn to a UITextField so the user can edit the value of that row.

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if(indexPath.section == 1 &&
       indexPath.row < [item.entries count])
    {
        ListDetailCell *tmpCell = ((ListDetailCell*)[self tableView:tvEntries cellForRowAtIndexPath:indexPath]);
        tmpCell.lbTitle.hidden = true;  // <- cell to hide
        tmpCell.tfTitle.hidden = false; // <- textfield to show
    }
}

For any reasons it seems that my changes on the controls don't get applied.

Any hints here? Thx in advance

Have you tried calling reloadRowsAtIndexPaths:withRowAnimation: after applying your updates? Like:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if(indexPath.section == 1 &&
       indexPath.row < [item.entries count])
    {
        ListDetailCell *tmpCell = ((ListDetailCell*)[self tableView:tvEntries cellForRowAtIndexPath:indexPath]);
        tmpCell.lbTitle.hidden = true;  // <- cell to hide
        tmpCell.tfTitle.hidden = false; // <- textfield to show

        //reload the cell
        [tableView reloadRowsAtIndexPaths: [NSArray arrayWithObject: indexPath]
         withRowAnimation: UITableViewRowAnimationNone];
    }
}

In general, updates made to a displayed cell will not appear unless you explicitly tell the table to reload that cell (or to reload everything by calling reloadData.
