用户点击全屏图像时隐藏导航栏和工具栏？

I need help with setting up this functionality. From the first view controller the user taps a thumbnail image to go to this view controller that displays the image full screen. I have customized the look of the navigation bar so that it looks different from the rest of the app, so the same navigation bar is not linked from the previous.I need help with setting up this functionality.
