hide/show Scrollview in Navigation Contoller
<p>I am using a Navigation Controller. On top of the AppDelegate window I added a view that contains a scrollview and toolbar that I want to be using throughout the app. They appear fine on all the view controllers that I am using in the navigation controller. Now I would like to be able to hide and show them from each view controller.
I cant figure out how that should work,
any suggestions?</p>
