I've tried this and have no problems, its all done in IB with no additional code required ...
- Start a new project, "Single View Application" using story boards
- Select storyboard and delete the views its produced.
- Drag on a new Navigation Controller (it will bring a table view with it)
- Delete the table and the table view controller, so you are just left with the Navigation Controller
- Drag on a normal view controller
- Right Click and drag from the Navigation controller to the new View and choose "Relationship - Root View Controller"
- Drag a "Bar Button Item" on to the Navbar which should be visible on the top of your ViewController, you can rename this Forward if you wish.
- Now drag on another view controller which is the one your "Forward" button will push in to view.
- Right Click and drag from the bar button to the 2nd View Controller, and choose "Push"
Run the project and you will get a Single view with a Navbar and your button, clicking your button will Push the other view and give you a Back Button to return to the first View Controller. I'll try and post a picture of my storyboard if it helps.
