Question

I currently have a UIAlertview displaying a grouped table view and have spent all week getting it to work just right, i left what should have been the easiest part till last, adding the accessories. All i want is to have the row show up as checked when it is tapped. This sounds simple enough an at first glance works fine. If i tap the cell at 0,0 it gets ticked BUT, if i then scroll down i also end up with 2,1 being ticked and 3,6 (and 0,0 gets unticked again). I have looked at This Question and tested their code on another grouped table and it works fine but made no difference to my Alert Table.

This is the code i am using

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

    cell.accessoryType = UITableViewCellAccessoryCheckmark;

}

I see no way that this can modify more than one cell. I have put a break point there and it is only ever called one time per tap.

Cellforrowatindex method:

- (UITableViewCell *)tableView:(UITableView *)tableView
     cellForRowAtIndexPath:(NSIndexPath *)indexPath {

      static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";

      NSArray *listData =[self.data objectForKey:

      [self.sortedKeys objectAtIndex:[indexPath section]]];

      UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier];

     if(cell == nil) {

         cell = [[[UITableViewCell alloc]
             initWithStyle:UITableViewCellStyleDefault
             reuseIdentifier:SimpleTableIdentifier] autorelease];
      }

    NSUInteger Row = [indexPath row];
    cell.textLabel.text = [listData objectAtIndex:Row];

    return cell;
}

Thanks.

I’m thinking that because you’re reusing UITableViewCells, once you change one cell accessoryType, it may affect the rest of the cells in the table view.

Inside your cellForRowAtIndexPath after you get the cell object, do the following :

cell.accessoryType = UITableViewCellAccessoryNone

Hope it helps.
