The result of vc2 :

How to set that in storyboard?

Answer 1

If you are pushing view controller from VC1 to VC2 through navigation controller then write below line in VC2's viewWillAppear method.

If you are using Swift 3.0 :

 self.navigationController?.navigationBar.isHidden = false

 self.navigationItem.setHidesBackButton(false, animated:true);

Answer 2

I see your Controller1's navigation bar have left bar button item and right bar button item.

You can drag a button item to your VC2's navigation item.
