So I finally released my first game and I made it not work very well on Iphone 5 and Ipod touch 5 because I set the made a plane the background and tested to see if it filled the screen on the Iphone 4. It does not on the Iphone 5 and there are other problems because of this to.
My question is how can I check to see what device my game is running on? If I knew this I think I could fix the problem.
