UIBarButton differences between View and tableViewControllers?

I have a tab bar iPhone application.

Tab bar #1 has a table view controller. It pushes a detail screen onto the stack. On the top right hand corner there is a UIBarButton that calls and action sheet. This is all built programmatically through code and all works fine.

Tab bar #2 calls a table view controller than then loads a map view. The map view annotation callouts then open up a detail screen. On this screen, I'd like a UIBarButto开发者_如何转开发n. So far, I cannot get this to work. The button does not show up.

Any ideas why?

Thanks, J
