UITableView with clickable, sortable headers

I'm trying to take an existing UITableView and add column headers which are clickable and sortable. I've looked at AQGridView but I can't see a way to g开发者_如何学JAVAet that sort of effect. At the moment I'm thinking of adding a UIButton above the UITableView then styling it to make it look like a header. Is this an awful idea?

On the iPhone there is not really enough space to do desktop program style column sorting.

The recommended way to to this is to put a UISegmentedControl as the titleView of the UINavigationBar or a UIToolBar.

Looks pretty, too.
