view - Mi IAP no funciona. Errores en func Paymentqueue

in-app-purchase

Question

Cuando hago clic en cualquiera de mis IAPS, aparece un mensaje que dice que el IAP ya fue comprado (que no es el caso) y se restaurará de forma gratuita, luego no pasa nada, el IAP no se ejecuta.

Esto es lo que obtengo en mi consola:

No Value.
IAP is enabled, loading...

true
Product Request
Product Added
IAP id
Remove Ads
Removes ads from the app.
2
Buy: IAP id
Add Payment
nil
default: Error

Aquí está mi código:

¡Encontré la solución!

Borrar

SKPaymentQueue.defaultQueue().addTransactionObserver(self) 

donde sea que lo tenga y lo coloque una vez (SOLO UNA VEZ) en un lugar donde se ejecutará cada vez que su aplicación se inicie (lo puse en viewDidLoad ()).

Esto verificará todas las transacciones sin terminar y las terminará una vez que la aplicación se haya cargado, eliminando así cualquier posible error antes de que sus usuarios activen un IAP.

(Si esta respuesta, o esta pregunta te ayudó, no olvides votar a favor;))

PD: Además, este no era mi problema, pero asegúrese de terminar Transaction () para cada PurchaseState como aquí:

func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
        print("Add Payment")

        for transaction:AnyObject in transactions{
            let trans = transaction as! SKPaymentTransaction
            print(trans.error)
            switch trans.transactionState{
            case .Purchased:
                print("IAP unlocked")
                print(p.productIdentifier)

                let prodID = p.productIdentifier as String
                switch prodID{
                case "IAP id":
                    print("Keep on")
                    keepOn()
                default:
                    print("IAP not setup")
                }
                queue.finishTransaction(trans)
                break
            case .Failed:
                print ("Buy error")
                queue.finishTransaction(trans)
                break
            default:
                print("default: Error")
                break
            }
        }
    }

Nunca olvides esto:

 queue.finishTransaction(trans)
