My first screen is a navigation controller then comes my login view and if I log in and i see my Slide-out Sidebar Menu. I log in with iOS7 but backbutton is superimposed on menu-slide but i can see my menu-slide in iOS 8 and it does not appear the backbutton.
When I pass from login to Slide-out Sidebar Menu view, I use segue "show detail" not inherit the backbutton.
