Question

I have a tableview that has groups. I would like to add a dummy cell at the top of each group, but not add it to the data. I dont want it saved. So if the top cell is clicked, its data passed will be blank and I can handle the passed view differently. I currently am configuring the cells manually.

So if group one had two entries, the display of those two entries would be prepended with a fake entry at what would be index 0

Below is a preview of what I am trying to do.

PS: Can one cell have a different disclosure icon? Does that break Interface Guidelines?

It would be something like this, you are not really adding anything to your model, you are just modifying your view:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }

    if ([indexPath row] == 0) {
        //And any other default behavior
        [[cell textLabel] setText:@""];
    }
    else{
        //Your code for each cell


    }
    return cell;
}

The HIG doesn’t mention anything about having different disclosure icons:

iOS includes some table-view elements that can extend the functionality of table views. Unless noted otherwise, these elements are suitable for use with table views only.
