I have a UIViewController that initially is of a white background and allows the user to color in the UIImageView of a certain color by touch events. When all is done, I would like a way to highlight or show the uncolored areas (the remaining white areas) of the UIImageView. Is there a nice way to implement this. I have tried messing with CGBitMap methods but I have not been successful without any errors in code.
Thanks!
Could you simply change the background color of your UIViewController?
