I have added a consumable In App Purchase to my app. I am able to purchase it but then when I try to purchase it again it says that I have already purchased it so it will download again. The type is definitely consumable. Where am I going wrong? Thanks
func purchasePoints(sender:AnyObject) {
//Purchase
buyConsumable()
}
func buyConsumable(){
print("About to fetch the products");
// We check that we are allow to make the purchase.
if (SKPaymentQueue.canMakePayments())
{
var productID:NSSet = NSSet(object: "com.companyname.appname.coins");
var productsRequest:SKProductsRequest = SKProductsRequest(productIdentifiers: productID as! Set<String>);
productsRequest.delegate = self;
productsRequest.start();
print("Fething Products");
}else{
print("can not make purchases");
}
}
func productsRequest (request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
print("got the request from Apple")
var count : Int = response.products.count
if (count>0) {
var validProducts = response.products
var validProduct: SKProduct = response.products[0] as SKProduct
if (validProduct.productIdentifier == "com.companyname.appname.coins") {
print(validProduct.localizedTitle)
print(validProduct.localizedDescription)
print(validProduct.price)
buyProduct(validProduct);
} else {
print(validProduct.productIdentifier)
}
} else {
print("nothing")
}
}
func buyProduct(product: SKProduct){
print("Sending the Payment Request to Apple");
var payment = SKPayment(product: product)
SKPaymentQueue.defaultQueue().addPayment(payment);
}
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)
break;
case .Failed:
print("Purchased Failed");
SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
break;
// case .Restored:
//[self restoreTransaction:transaction];
default:
break;
}
}
}
}
Did you see this messages in console log:
and
or
?
If not, it seems like you did not add
somewhere before adding payment to queue. Try to add this in your buyConsumable method.
In according to https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/StoreKitGuide/Chapters/DeliverProduct.html
Try this with existing transaction, but be sure that it is consumable.
