iOS7 Custom ViewController transition and Top Layout Guide

Question

I implemented a custom UIViewController Transition in my App, which replaces the navigation controllers built in push animation.

Everything works so far, except the topl

Answer 1

I found a way. First uncheck "Extend Edges" property of controller after that navigation bar will get in dark color. Add a view to controller and set top and bottom LayoutConstraint -100. Then make view's clipsubview property no (for navigaionbar transculent effect). My english is bad sorry for that. :)
