The source code, MKStoreKit, contains four objective c files. MKStoreManager.h/m and MKStoreObserver.h/m and five server side files. The MKStoreManager is a singleton class that takes care of *everything*. Just include StoreKit framework into your product and drag these four files into the project. You then have to initialize it by calling [MKStoreManager sharedManager] in your applicationDidFinishLaunching. From then on, it does the magic. The MKStoreKit automatically activates/deactivates features using your userDefaults. When a feature is purchased, it automagically records it into NSUserDefaults.
