I am implementing in app purchase (non consumable type – songs ).when a user taps buy for every song purchase i call startPurchase funtion.my song content is delivered via my server.
In that when i purchased something and again try to re purchase the same, it is not treated as restore of purchase.it makes a new purchase.the delegate methods are called multiple times
Actually what is my problem is, i tap buy and proceed with the payment, and purchased that item.
Again when i try to buy the same item the apple alert says as “You have already purchased this item, tap ok to download” when i tap “OK“.this is not coming under SKPaymentTransactionStateRestored instead it goes to SKPaymentTransactionStatePurchased.why this is happening? pls help
Please help me out

I think your problem add transaction server duplicate reflecting
Try below code for avoid add transaction server duplicate may be it’s worked:
In your i am check the transaction server is added or not below code:
hasAddObserver Variable static bool datatype is check if already added easy to added check transaction server!
