title: Rounded button above the UISCROLLVIEW
body: <p>I have been working in a project which has a uiscroll view where the uiscroll view size is set programatically with height 225 and width is self. I have created two uiimageView where it displays two images and I have animated it by moving using a page view controller. Finally the image moves atomically like a slide show with page view controller. I have removed the navigation controller do I need to keep a back button for navigation when I place a unbutton above uiscrollview it was stating like scrollview ambitious scrolling content. I need to place a rounded back button above scroll view. I have attached the image of my storyboard. When I tried to place a button it is not visible in stimulator <a href="https://i.stack.imgur.com/P03z6.png" rel="nofollow noreferrer">header scroll view is the UISCROLLVIEW where the animated image is placed</a></p>
