I am implementing in-app purchase to my iPhone App. I am following with this tutorial http://xcodenoobies.blogspot.com/2012/04/implementing-inapp-purchase-in-xcode.html and everything working fine.
But in the above tutorial purchase state is saving in the Phone KeyChain Utility. We can able to purchase it only once.
The second time when i downloaded the App it installs with purchased state .
In in-app purchases purchase should be unique to Apple ID or Device or Both ?
Thanks.
Yes, if you create product as Non-Consumable then it will allow only once to buy.
