I read about the In App Purchases tutorial from Introduction to In App Purchases. Another good tutorial is In App Purchases walkthrough . I tried to use raywenderlich example. He is using NSNotification. I prefer to use block NSNotification , so I changed some code from his tutorial and put it on github.
I love my new library https://github.com/saturngod/IAPHelper . It’s more easier to use In App Purchases than Native. It already support ARC.
I need to do subscription method in the library and still not start yet.
