If you’ve been following my tutorials on OpenGL ES 2 for iOS, by the time you finish Texturing (Part 6 or so) you’ll have a lot of code crammed into a single UIViewController. This is intentional: the tutorials are largely self-contained, and only create classes and objects where OpenGL itself uses class-like-things.
…but most of the code is re-used from tutorial to tutorial, and it’s getting in the way. It’s time for some refactoring.
