Question

I may not be using a proper term here, but ..

Suppose you have a deck of cards represented as one big image. From this image, i’d like to find a way to reference each individual card separately. How can this be done using Objective-C?

Answer 1

The following will provide access to part of the image, numbers will need to obviously be refined

CGImageRef bigImage = [UIImage imageNamed:@"bigImage.png"].CGImage;

CGImageRef partOfBigImage = CGImageCreateWithImageInRect(bigImage, 
                 CGRectMake(0, 0, 200, 50));

UIImage *partOfImage = [UIImage imageWithCGImage:partOfImageAsCG];
