@Alexi's answer, to remove the exit link, did not work for me, after removing the exit link, I deleted UINavigationViewController's Relationship Segue , in UIViewController , which had UINavigationItem , I could not delete.
Then I could remove the navigation item in my UIViewController.
Finally, I added Relationship Segue in Xcode 7 as follows:
- In the Control storyboard, drag from
UINavigationController to UIViewController - Select
root view controller under Relationship Seque
