Slide Xcode Puzzle for iPhone

I require someone to write a game which takes a photo and divides it up into squares, which are then scrambled around, omitting the bottom right square. The images can only be moved into the empty space one square at a time. When all the squares are positioned into the correct place a "congratulations" view should be pushed onto the screen. ## Deliverables The image is to be set via a variable and not pre-tiled.
