【问题描述】：

我正在尝试向我的应用程序添加一个恢复按钮，我有一个非消耗品 inApp 购买并且购买部分工作正常。我有一个调用这两种方法的按钮：

product_id = "RemoveAdsIAP";
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()

这是购买代码：

func buyConsumable()
    succssessIAP = false
    if (SKPaymentQueue.canMakePayments()) 
        var productID:NSSet = NSSet(object: self.product_id!);
        var productsRequest:SKProductsRequest = SKProductsRequest(productIdentifiers: productID);
        productsRequest.delegate = self;
        productsRequest.start();
     else 
        displayErrorAlert()
    


func buyProduct(product: SKProduct)
    var payment = SKPayment(product: product)
    SKPaymentQueue.defaultQueue().addPayment(payment);


func productsRequest (request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) 
    var count : Int = response.products.count
    if (count>0) 
        var validProducts = response.products
        var validProduct: SKProduct = response.products[0] as SKProduct
        if (validProduct.productIdentifier == self.product_id) 
            buyProduct(validProduct);
         else  
     else 
        displayErrorAlert()
    


func request(request: SKRequest!, didFailWithError error: NSError!) 
    activityIndicatorShop.stopAnimating()
    UIApplication.sharedApplication().endIgnoringInteractionEvents()
    displayErrorAlert()


func paymentQueue(queue: SKPaymentQueue!, updatedTransactions transactions: [AnyObject]!) 
    succssessIAP = false
    for transaction:AnyObject in transactions 
        if let trans:SKPaymentTransaction = transaction as? SKPaymentTransaction
            switch trans.transactionState 
            case .Purchased, .Restored:
                if (product_id == "GetNextFactIAP" && succssessIAP == false) 
                    startController.getData()
                    startController.hideContainerView()
                    succssessIAP = true
                
                if (product_id == "RemoveAdsIAP" && succssessIAP == false) 
                    NSUserDefaults.standardUserDefaults().setBool(true, forKey: "viewAdsBool")
                    NSUserDefaults.standardUserDefaults().synchronize()
                    startController.removeOnce()
                    disableAds(true)
                    succssessIAP = true
                
                SKPaymentQueue.defaultQueue().finishTransaction(transaction as SKPaymentTransaction)
                break;
            case .Failed:
                SKPaymentQueue.defaultQueue().finishTransaction(transaction as SKPaymentTransaction)
                activityIndicatorShop.stopAnimating()
                displayErrorAlert()
                UIApplication.sharedApplication().endIgnoringInteractionEvents()
                break;
            default:
                break;
            
        
    
    

当我按下按钮时没有任何反应，我添加了一条日志语句来检查是否调用了 updatedTransactions 方法，但没有，有什么问题？

【问题讨论】：

您的问题需要更具体。哪个代码被调用，哪个不是？按钮代码？ updatedTransactions 方法？等等。代表设置了吗？你实施失败的方法吗？那些叫？如果是这样，传递了什么错误？

updatedTransactions 没有被调用，我会添加完整的代码，因为我不知道缺少什么。

【参考方案1】：

您的 products_id 格式错误。 应该更像

product_id = "com.xxxxxxxxx.RemoveAdsIAP"
