Hide navigation bar, but when I transition to the previous view (popped) it shows the old back button temporarily. Why?
问题 I have view controllers in a navigation controller (root: RootViewController , second: ReadingViewController ), but in the second view controller I want to disable the navigation bar for a UIToolBar (as I don't need the title and want more buttons, like in iBooks or the Facebook app). Problem is, when I hide the navigation bar in the second view, it appears randomly for a second again when I pop the view controller (go back). When I pop the view controller the back button appears for a second
