Question

In Phone app, in contacts tab on tab bar, there is things in table view.

These are between contact cells and bright gray, and have a little transparent effect and a alphabet character on it. They are separating by alphabet group.

I think they are a kind of table view cell and want to know how to use it. (name or sample code)

Answer 1

If I understand you correctly, they are called table header views, and you add them by implementing

-(NSString*)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section

in your table view data source.
