Im making a tile-based game with a grid of 5x6 tiles, and eachtile changes it's image when you tap on it(with the Touch Up Inside event). It's not nessecary but I would like to make it so that you can slide your finger over many buttons with only one touch(just a slide) therefore reducing the need to tap each one individually and speeding up game play. Is this possible with Interface Builder's events? or will I need a subclass of UIButton? suggestions? Help is very much appreciated
