auto renewal in app purchases?

I've been programming in Xcode for a year now, last time i attempted to us开发者_C百科e in app purchases i gave up after two weeks of getting nothing done. I am ready to try again but so far i have gotten no progress and everything i tried has failed.

I've also tried the simpleSDK tutorial on YouTube and when i pressed the purchase button on my phone nothing happened.

Can someone supply good code that works?

You might want to use MKStoreKit then
