Hi Iain,
There isn't such a thing as a bottom navigation bar, what you're referring to is called a toolbar. In Interface Builder, just place a UIToolBar under the UITableView (to do that you'll have to use a UIViewController instead of a UITableViewController, please refer to PeopleViewController.xib for an example of using a UITableView with other controls in a UIViewController). Again, all this has nothing to do with STV, STV just manages the UITableView control on your view controller.
