iOS In-App purchase for Non-Consumable affected by IPV6 - ios

Question

I implement IAP using Swift to unlock my game stage. It works well on IPv4. So I submit this binary for review and get rejected by Apple when they tested on IPv6 network.
Reject binary reason:
We discovered one or more bugs in your app when reviewed on iPhone running iOS 9.3.2 on Wi-Fi connected to an IPv6 network.
Specifically, after we purchase the In App Purchase, the level does not unlock.
I put break point for every case but the program didn't go inside any 1 of them when I running on IPv6 network.
Here my code for do purchase:
func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
print("Received Payment Transaction Response from Apple");
for transaction:AnyObject in transactions {
if let trans:SKPaymentTransaction = transaction as? SKPaymentTransaction{
switch trans.transactionState {
case .Purchased:
print("Product Purchased");
SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
self.levelButtonHalloween.enabled = true
lockImage.removeFromSuperview()
Overlay.removeFromSuperview()
userSettingDefaults.setBool(true, forKey: "enableHalloween")
userSettingDefaults.synchronize()
DesertOver50 = userSettingDefaults.boolForKey("enableHalloween")
buyBottom.removeFromSuperview()
backgroundImage.removeFromParent()
backgroundImage = SKSpriteNode(imageNamed: "StageSelect_Background2")
backgroundImage.size = self.frame.size
backgroundImage.position = CGPoint(x: frame.size.width / 2, y: frame.size.height / 2)
backgroundImage.anchorPoint = CGPointMake(0.5, 0.5)
backgroundImage.zPosition = 0
addChild(backgroundImage)
break;
case .Failed:
print("Purchase Failed");
SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
break;
case .Restored:
print("Transaction restored")
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
self.levelButtonHalloween.enabled = true
lockImage.removeFromSuperview()
Overlay.removeFromSuperview()
userSettingDefaults.setBool(true, forKey: "enableHalloween")
userSettingDefaults.synchronize()
DesertOver50 = userSettingDefaults.boolForKey("enableHalloween")
buyBottom.removeFromSuperview()
backgroundImage.removeFromParent()
backgroundImage = SKSpriteNode(imageNamed: "StageSelect_Background2")
backgroundImage.size = self.frame.size
backgroundImage.position = CGPoint(x: frame.size.width / 2, y: frame.size.height / 2)
backgroundImage.anchorPoint = CGPointMake(0.5, 0.5)
backgroundImage.zPosition = 0
addChild(backgroundImage)
default:
break;
}
}
}
SKPaymentQueue.defaultQueue().removeTransactionObserver(self)
}
I also implement button for restore purchase and it work well for both ipv4 and ipv6.
Here the code for restore purchase:
func restorePurchaseButtonAction(){
button_Clicked()
if (DesertOver50 == false){
if (SKPaymentQueue.canMakePayments()) {
// Enable SKPayment as soon as possible during viewdidload
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
}
}else{
let alert = UIAlertController(title: "It's already unlocked ¬_¬", message: "Your have already unlocked or purchased the item(s)", preferredStyle: .ActionSheet)
let ok = UIAlertAction(title: "OK", style: .Cancel) { action -> Void in
}
alert.addAction(ok)
alert.popoverPresentationController?.sourceView = view
alert.popoverPresentationController?.sourceRect = self.frame
self.view?.window?.rootViewController?.presentViewController(alert, animated: true, completion: nil)
}
}
Anyone have experience this before? Any different implement IAP on IPv4 vs IPv6? What should I do next?

Answer 1

Do you check your settings in ItunesConnect whether in-app purchase is registered correctly? Remember to put
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
in viewDidLoad. This issue has been plaguing me too.

Answer 2

Thank you for your advice. My ituneConnect seem ok.
that SKPaymentQueue.defaultQueue().addTransactionObserver(self) is root cause
of my problem.
Scenario 1:
Item completely purchase but stage not unlock =>Fail
func buyNonConsumable() {
button_Clicked()
print("About to fetch the products");
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
// We check that we are allow to make the purchase.
if (SKPaymentQueue.canMakePayments()) {
let productID:NSSet = NSSet(object: self.product_id!);
let productsRequest:SKProductsRequest = SKProductsRequest(productIdentifiers: productID as! Set<String>);
productsRequest.delegate = self;
productsRequest.start();
print("Fething Products");
} else {
print("can't make purchases");
}
}
Scenario 2: Item auto unlock itself when app start without need to login =>Fail
override func didMoveToView(view: SKView) {
// In-App button and function call
if(DesertOver50 == false) {
product_id = "xxxxxxxx";
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
addBotton();
Scenario 3: Working properly
func buyProduct(product: SKProduct) {
print("Sending the Payment Request to Apple");
let payment = SKPayment(product: product)
SKPaymentQueue.defaultQueue().addPayment(payment);
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
}
From what I understand scenario 2 should best solution but it fail.
Since code now working perfectly, I assume scenario 3 is the solution.
