Photo hunt game: high level design help
I'm in the beginning stages of creating a photo hunt/spot the difference game. The type where players must pick out differences between two similar photographs.
As a proof of concept, I created an incredibly crude prototype using almost entirely interface builder. I have 2 images on screen, with a bunch of nearly invisible buttons placed over differences in the pictures. When one of the invisible buttons is pressed, an alert pops up saying "You found a difference."
My question is from a design perspective, is there a better method of implementing this game programmatically? There must be a better way than littering the screen with invisible buttons and having 20 nibs for 20 pictures.
Since these photo hunt games are so popular, there must be some "standard" method of design/implementation i don't know of.
