In app purchase restore button doesn't cause any action? - swift

Question

I am new to working in in-app purchases. I have set up my app to allow multiple non-consumable in-apps. If it is a first time purchase it works perfectly. If I try and click the buy button again it shows "This in-app has already been purchased etc. etc." once you click Okay, it does nothing. I have noticed it only shows "Okay" as the option and not "Cancel" and "Okay". In my test app, it shows both and works great.` #IBOutlet weak var buyProductID: UILabel!
let product1 = "TestAd.com"
#IBOutlet weak var adView1: UIView!
func buyProduct1(product1: SKProduct){
print("Sending the Payment Request to Apple 1");
let payment1 = SKPayment(product: product1)
SKPaymentQueue.default().add(payment1);
}
#IBAction func product1Btn(sender: AnyObject) {
buyProductID.text = "Product1"
print("About to fetch the product... 1")
// Can make payments
if (SKPaymentQueue.canMakePayments())
{
let productID1:NSSet = NSSet(object: self.product1);
let productsRequest1:SKProductsRequest = SKProductsRequest(productIdentifiers: productID1 as! Set<String>);
productsRequest1.delegate = self;
productsRequest1.start();
print("Fetching Products 1");
}else{
print("Can't make purchases 1");
}
}
func purchase1ViewDid(){
if (UserDefaults.standard.bool(forKey: "purchased1")){
adView1.isHidden = true
print("No ads for 1")
} else {
print("Yes ads 1")
}
}
func productsRequest (_ request: SKProductsRequest, didReceive response: SKProductsResponse) {
//PRODUCT 1
let count1 : Int = response.products.count
if (count1>0) {
let validProduct1: SKProduct = response.products[0] as SKProduct
if (validProduct1.productIdentifier == self.product1) {
print(validProduct1.localizedTitle)
print(validProduct1.localizedDescription)
print(validProduct1.price)
buyProduct1(product1: validProduct1);
} else {
print(validProduct1.productIdentifier)
}
} else {
print("nothing 1")
}
}
func request(_ request: SKRequest, didFailWithError error: Error) {
print("Error Fetching product information 1");
}
func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions1: [SKPaymentTransaction]) {
print("Received Payment Transaction Response from Apple 1");
for transaction1:AnyObject in transactions1 {
if let trans:SKPaymentTransaction = transaction1 as? SKPaymentTransaction{
switch trans.transactionState {
case .purchased:
if buyProductID.text == "Product1" {
print("Product Purchased 1");
SKPaymentQueue.default().finishTransaction(transaction1 as! SKPaymentTransaction)
// Handle the purchase
UserDefaults.standard.set(true , forKey: "purchased1")
adView1.isHidden = true
}
break;
case .failed:
print("Purchased Failed 1");
SKPaymentQueue.default().finishTransaction(transaction1 as! SKPaymentTransaction)
break;
case .restored:
print("Already Purchased 1");
SKPaymentQueue.default().restoreCompletedTransactions()
// Handle the purchase
UserDefaults.standard.set(true , forKey: "purchased1")
adView1.isHidden = true
break;
default:
break;
}
}
}
}

Non-consumable purchases can only be purchased once, so this is the expected behavior. The message is displayed because you can only purchase the non-consumable item once, and it remains associated with the account. It thinks that since you have purchased the item already, that you simply want to restore it. As a side note, for testing purposes, IAPs have to be tested using a real device, so the simulator won't test IAPs correctly.
