编辑：奇怪的是,将iPad更新到iOS 8.3修复了问题.关于为什么发生这个问题的任何想法？我应该将应用程序更改为仅支持iOS 8.3及更高版本？

要测试应用程序,我使用的是TestFlight,相同的网络连接和相同的Apple ID.

我在应用内购买中使用的代码如下：

func inApp() {
    if (SKPaymentQueue.canMakePayments())
    {
        var productID:NSSet = NSSet(object: product_id);
        var productsRequest:SKProductsRequest = SKProductsRequest(productIdentifiers: productID as Set<NSObject>);
        productsRequest.delegate = self;
        productsRequest.start();
    }else{
        displayAlert()
    }
}
 
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 == product_id) {
            println(validProduct.localizedTitle)
            println(validProduct.localizedDescription)
            println(validProduct.price)
            buyProduct(validProduct);
        } else {
            println(validProduct.productIdentifier)
        }
    } else {
        displayAlert()
    }
}
 
 
func request(request: SKRequest!,didFailWithError error: NSError!) {
    self.displayAlert()
}
 
func paymentQueue(queue: SKPaymentQueue!,updatedTransactions transactions: [AnyObject]!)    {
    for transaction:AnyObject in transactions {
        if let trans:SKPaymentTransaction = transaction as? SKPaymentTransaction{
            switch trans.transactionState {
            case .Purchased:
                SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
                if product_id == "com.shv.FrenzyTenLives" {
                    defaults.setInteger(10,forKey: "totalLives")
                } else if product_id == "com.shv.FrenzyFiveLives" {
                    defaults.setInteger(5,forKey: "totalLives")
                } else if product_id == "com.shv.FrenzyInfiniteLives" {
                    defaults.setBool(true,forKey: "infiniteLives")
                } else if product_id == "com.shv.FrenzyShield" {
                    defaults.setInteger(5,forKey: "shieldValue")
                } else if product_id == "com.shv.FrenzyRemoveAds" {
                    defaults.setBool(true,forKey: "adsRemoved")
                    adBanner.hidden = true
                }
                break;
            case .Failed:
                SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
                self.displayAlert()
                break;
            case .Restored:
                SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
                if product_id == "com.shv.FrenzyTenLives" {
                    defaults.setInteger(10,forKey: "infiniteLives")
                } else if product_id == "com.shv.FrenzyRemoveAds" {
                    defaults.setBool(true,forKey: "adsRemoved")
                    adBanner.hidden = true
                }
                break;
            default:
                break;
            }
        }
    }
}
