UIStoryboard relationship segue "root view" hides tabbar

Question

I've inherited project which main view based on UITabBarController with two tabs, each is UINavigationController with root view controller connected via Relationship "root view controller" segue. I need to add 3d one.

I do the same for it - add UINavigationController scene, create relationship to UITabBarController as "view controllers". Then create segue from this new navigation controller to needed root view controller. It works, but when I select this 3d tab, UITabBar disappears. What could be happening here?

Answer 1

The solution was trivial... IB flag "Hide Bottom Bar on Push" actually hides tabbar not only when pushed, but always for this view controller. Very strange behavior btw, seems like a bug in SDK.
