I've been looking to implement my own interactive custom view controller transition without using UIPercentDrivenInteractiveTransition since I want full control of how my views will look at various stages of the transition. Unfortunately I cant find anything online, and all the examples use UIPercentDrivenInteractiveTransition.

What i've done: -setup my animator to implement the UIViewControllerInteractiveTransitioning protocol -implemented 

- (void)startInteractiveTransition:(id<UIViewControllerContextTransitioning>)transitionContext {

Where i'm lost -I need to update the state of my views while the user is interacting with a pan gesture recognizer, but after poking into the UIViewControllerContextTransitioning protocol and noticing the updateInteractiveTransition method, i cant figure out where I would implement this last missing piece.

He does it in [SCPercentDrivenInteractiveTransition.h](https://github.com/stringcode86/UIPercentDrivenInteractiveTransitionWithCABasicAnimation/blob/master/InteractiveTransition/SCPercentDrivenInteractiveTransition.h) and [.m](https://github.com/stringcode86/UIPercentDrivenInteractiveTransitionWithCABasicAnimation/blob/master/InteractiveTransition/SCPercentDrivenInteractiveTransition.m). – bcattle Jan 07 '15 at 01:32
