I'm developing an app and have come against a strange issue I can't find the answer for - when testing the app on an iPhone 5 the whole app display window is shrunk down to what looks like a 3.5 size display (the top and bottom of the screen are black and even the status bar is pushed down). When I test the app on an iPhone 5s running iOS 8 it displays full screen as expected.
Also when testing in the iOS simulator for iphone 5, and 5s it displays as expected. I'm using xcode 6 for development.
Any help would be greatly appreciated.
