Detail Text View of Cell not showing?

Hi I started writing a split view app for iPad using the split-view template. In the root view controller (the table view on the left) I am trying to set the detail te开发者_运维技巧xt label of the cells like this:

cell.detailTextLabel.text = [NSString stringWithFormat:@"%d", indexPath.row];

However when I run the app only the main text label (the label on the left of the cell). There is nothing that shows up in the detail label.

What am I doing wrong?

make sure that your cell is created as UITableViewCellStyleSubtitle

In cellForRowAtIndexPath method

 static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text =  @"Heading";
cell.detailTextLabel.text = @"DetailValue";

 return cell;

Options :

UITableViewCellStyleValue1, // like in Settings App )

UITableViewCellStyleValue2, // Contacts style

UITableViewCellStyleSubtitle // DetailText in Grey.
