This question references the excellent SWRevealViewController library.
I have a simple implementation of a homeVC (front) and a menuVC (rear). Both VCs are imbedded in navigation controllers. I use a standard "hamburger" UIBarButtonItem to trigger the reveal segue from homeVC to menuVC. All is working happily.
My question is: I would like to trigger a transformation where the hamburger changes from the standard icon (state 0), to something else (state 1). I would like to implement this so that the transformation is tied to the degree to which the reveal segue is complete.
I don't want a cut and paste answer. I'd prefer some ideas how this could be accomplished theoretically?
