I use a navigation-based iOS application. I want to make a background similar to desktop wallpaper in Android. So when I go to another View the current View and it's content goes outside of the screen but the background image slightly moves only. See a sample screenshot here.

Why not have the base subview set to the size of the background wallpaper (ie larger than the screens width) and start with it left aligned. Then have a paged UIScrollView on top of that. When the user scrolls the UIScrollview, hook into the UIScrollViewDelegate method - scrollViewDidScroll: and pass it through the the base subview, telling it to animate in accordance.

This shouldn't be too hard but you'll probably want to tweak it a bit to get the feel you want.Try playing about with the various delegate methods in the UIScrollViewDelegate protocol to determine the best time to start the animation.
