Using UIViewController Transition Delegate break menu display

Hello,

Thanks first for your work.

I just run down a problem. I'm using a transition delegate from a VC A to show a VC B. The VC B contain the menu

` From VCA:

navigationController?.delegate = self navigationController?.showViewController(VC_B, sender: self) `

The menu does not appear. But if from VC B I present modally a VC C, when I dismiss this VC C, the menu appear on VC B.

This behavior is not present when I does not use the transition Delegate.

My questions:

• is it possible to force the redraw of the menu?
• could it be fixed ?!!

Thanks :-)

Can you show me some screenshots? It would be so helpful! Let me figure out where is wrong.
