Swift IOS 13，IAP - “无法连接到 Itunes Connect”

Question

我使用的是 IOS 13.5，在实施 IAP 时遇到了一些问题。我在构建以前的应用程序时使用了完全相同的代码，当我在与现在相同的物理设备上测试运行以前的应用程序时，支付工作正常。

我检查了互联网连接是否正常，证书看起来不错，Itunes Connect 中的 IAP 是“准备提交”，应用程序启用了 IAP，我已经制作了几个沙盒测试器，结果相同。我清理构建并重新启动计算机和设备，但它总是说 Code=2“无法连接到 Itunes Connect”

我什至尝试将构建上传到 Itunes connect 以查看它是否会有所作为，但没有。我显然遗漏了一些东西，并希望得到有关此问题的任何帮助。

呼吁开始购买：

IAPService.shared.purchase(product: .fullAccess)

IAP服务：

class IAPService: NSObject {

private override init() {}
static let shared = IAPService()

var products = [SKProduct]()
let paymentQueue = SKPaymentQueue.default()

func getProducts() {
    let products: Set = [IAPProduct.fullAccess.rawValue]
    let request = SKProductsRequest(productIdentifiers: products)
    request.delegate = self
    request.start()
    paymentQueue.add(self)
}

func purchase(product: IAPProduct){
    guard let productToPurchase = products.filter({ $0.productIdentifier == product.rawValue}).first else { return }
    let payment = SKPayment(product: productToPurchase)
    paymentQueue.add(payment)
}

func restorePurchases(){
    print("restoring purchases")
    GlobalVariables.hasFullAccess = false
    GlobalVariables.partialAccessArrayKeys.removeAll()
    paymentQueue.restoreCompletedTransactions()
    CheckPurchase.shared.checkUserPurchase()
}}

extension IAPService: SKProductsRequestDelegate {
    func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) {
        self.products = response.products
        for product in response.products {
            print(product.localizedTitle)
        }
    }
}

extension IAPService: SKPaymentTransactionObserver {
    func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
        for transaction in transactions {
            print(transaction.transactionState)
            print(transaction.transactionState.status(), transaction.payment.productIdentifier)
            print(transaction.debugDescription)
            if transaction.error != nil {
                print(transaction.error)
            }
            
        }
    }
}

extension SKPaymentTransactionState {
    func status() -> String {
        switch self {
        case .deferred: return "deferred"
        case .failed: return "failed"
        case .purchased: return "purchased"
        case .purchasing: return "purchasing"
        case .restored: return "restored"
        }
    }
}

IAP产品：

enum IAPProduct : String {
    case fullAccess = "se.marcusthuvesen.Torst.FullAccess"
}

应用代理：

class AppDelegate: UIResponder, UIApplicationDelegate, SKPaymentTransactionObserver {

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
    
}

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    UIApplication.shared.isIdleTimerDisabled = true
    FirebaseApp.configure()
    IAPService.shared.getProducts()
    SKPaymentQueue.default().add(self)
    //Load game texts from FireBase
    return true
}}

Answer 1

首先，您需要在 App Delegate didFinishLaunchingWithOptions 回调中将自己添加为 paymentQueue 的观察者。

您在哪里看到错误消息？您应该首先看到 SKProductsRequestDelegate 回调。
