I have an application which runs on a UINavigationController. Now I would like to add a UIToolbar element to the bottom of each screen. The Toolbar on the bottom should the be c
UINavigationController already has a toolbar. Just use
[self.navigationController setToolbarHidden:NO];
in the topmost view controller and
[self setToolbarItems:items];
in all your view controllers, where items is an NSArray
of that view controller's toolbar items.
EDIT: As for why your solution isn't working: your TOOLBAR_TAG
is probably not unique, that's why you're getting another subview. But as I said, you should use the included toolbar anyway.
