Hi So I have started making my first iPhone app! Its very, very simple, but I wan to slowly expand it. I need some help with a few things. Its really simple stuff, but I would really appreciate any help, thank you. 1. Firstly how can I set a background image? This is the first thing you see when you open the app. 2. I want this image to be able to rotate when I turn my device. 3. When I touch the screen I want the image to swap to my other chosen image. Would appreciate the help, so far only have set the name and icon of my app.
