Need help in 'App purchase programming guide' for iphone!

I have read the document for 'App purchase programming guide'. I am confused. It seems it does not apply to my circumstances. My apps is 'nonconsumable' type (purchase only once to use the apps) and the feature delivery is 'built-in product model' no server whatsoever. I also had added the开发者_StackOverflow storekit.framework. My question is do I need to add any additional coding? Based on the document it gives some sample code. Do I really need that for my case?

Yes. If you want to utilize In App Purchases, you can't just build against StoreKit.framework to your project. You need to create a UI so users can purchase items, which means you'll need to write code.
