How do I create a hiding/unhiding nav bar like what pinterest and many other apps is doing? I know the basic idea is to use the UIScrollView delegate and detect whether I am scrolling up or down and show the nav bar based on that. So should I also adjust the navcontroller view height if the nav bar is hidden? How does this work?
I have a sample project located on github that does exactly the pinterest/piictu style ‘hide the UINavigationController / UITabBarController stuff’
