Using Interface Builder after creating a new project and specifying Tabbed Application, I have two tab bar items. I would like to add more items, but I don't see how to do it in IB. Also, the tab bar items which I see I cannot select nor edit. How is that accomplished?
You just click on it in the simulated tab bar at the bottom of the view controller you added. Under Simulated Metrics "Bottom Bar" should be "Inferred" and there should be a tab bar item in the middle. It's possible if it has no title or image you can't see it; just click in the middle of the tab bar. Or click on it in the document outline (it should be shows with a blue star under the child view controller).
