This is our first post – and as such deserves a little bit of an introduction.  This website is going provide support and supplement material found in the How to Program Games iOS application.  The application merges a text book wtih a programming environment.  Allowing you to develop programs right on the pages of the lessons.  This greatly enhances the learning experience so you’ll understand concepts faster and better.  Right now the application is in it’s final stages of editing before being submitted to the app store.  The programming side of development is...
