When you embed your root viewController into a NavigationController, your sub ViewControllers automatically get a title bar. But they don’t get any Nav bar items.

To add something like a Welcome button for back navigation drag out a Navigation Item

And drop it into the middle of the navbar. Same for a button. Only a NavBar button is different than a Navigation item. It looks like this.

Drag this to the upper right hand corner of the nav bar and it should be OK.
