Rotation only in one ViewController

Question

I am trying to rotate one view while all other views (5) are fixed to portrait. The reason is that in that one view I want the user to watch pictures which he saved before.

None of these answers worked for me. Fundamentally, AppDelegate's method does not allow specification on which viewController. So either the topMost ViewController is rotatable, in which case the whole view controller hierarchy gets rotated, or nothing gets rotated.

However, I did find a promising answer in Child View Controller to Rotate While Parent View Controller Does Not
