How come my navigation control includes two bars one on the top and one on the bottom?

Question

In interface builder, I click on my tab bar controller and set the class of one of the tabs to Navigation Controller. This should set the this tab to be a navigation controller.

However, I get an additional bar at the the bottom like a toolbar. Is this normal behavior? How can I remove it?

Answer 1

In InterfaceBuilder, if you select the NavigationController item (usually in MainWindow.xib), you would notice a 'Show Toolbar' option in the Inspector that is selected. Deselect it and hopefully it'll go away.
