The view controller (left/right) always appears underneath the centre view controller.

Is it possible to make the revealed view appear on top?

I would like to know this, too! Would be very important for me! :)

I'm interesting too. Please, give us an answer.

You may want to look at SWRevealViewController. Depending on what you actually want to do It is just a matter of telling which are the rear or front controllers. You can design your logic to make the front controller to appear/dissapear (revealed in front) of one of the rear controllers.
