Every iPhone/iPad application has its sandbox area, where I can store files. When I use the simulator this area will be somewhere in the hard disk.

Between each one, I have 20 pixels. 40x40 pixels is too small to touch, but as I have 20 pixels of space between each button I can extend the button touch area to 60x60 pixels, making it easy to touch. I could simply using the dirty solution of creating a square 60x60 pixels trans...
