Users restore transactions to maintain access to content they’ve already purchased. For example, when they upgrade to a new phone, they don’t lose all of the items they purchased on the old phone. Include some mechanism in your app to let the user restore their purchases, such as a Restore Purchases button. Restoring purchases prompts for the user’s App Store credentials, which interrupts the flow of your app: because of this, don’t automatically restore purchases, especially not every time your app is launched.
If you submit app to store without button “Restore Purchase” maybe reject
How to solve problem ?
In your app declare function (Swift 2.0)
@IBAction func restorePurchase(sender:UIButton){
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
}
func paymentQueueRestoreCompletedTransactionsFinished(queue: SKPaymentQueue) {
print("received restored transactions: %i", queue.transactions.count);
if(queue.transactions.count > 0){
let productIdentifiers = NSSet(array: [PRODUCT_ID])
let productRequest = SKProductsRequest(productIdentifiers: productIdentifiers as! Set<String>)
productRequest.delegate = self
productRequest.start()
}else{
UIAlertView(title: "Notice", message: "You don't buy. Please buy for remove ads", delegate: nil, cancelButtonTitle: "OK").show()
}
}
Good luck
