ARKit : How to show / remove the view

[Slum]

Hi all,

I'm using ARKit (iPhone ARKit) to add an augmented reality functionality to my app.
So I want to show the view while rotating the phone (such as AroundMe), using didAutorotateToInterface delegate method.
That's working really good, but I want to add a show / hide methods to the ARKit (ARViewController) - I did not succeed in doing that.
(the best I can get "works", but there is a camera instead of the top status bar - that's strange).
How can I add / remove the ARView ?

Thank you
