Question

当我addPayment到空defaultQueue()时，我可以验证现在只有一个交易存在。但是，我的paymentQueue(_:updatedTransactions:)被多次调用，每次队列都包含原始事务的附加副本！

所以，我添加了付款（Xcode 6.4上的Swift 1.2，目标是OS 10.10）：

public func purchase() {
    if let product = product,
        let payment = SKPayment.paymentWithProduct(product) as? SKPayment
        where state == .Available {

            nslog("before purchase \(SKPaymentQueue.defaultQueue().transactions)")
            SKPaymentQueue.defaultQueue().addPayment(payment)
            nslog("after purchase \(SKPaymentQueue.defaultQueue().transactions)")
    }
}

将以下内容打印到控制台：

2015-08-04 14:12:28.887 MyApp[33753:10941171] before purchase [] --> StoreKitDelegate.swift/purchase() 65

2015-08-04 14:12:28.887 MyApp[33753:10941171] after purchase [<SKPaymentTransaction: 0x6080000032d0>] --> StoreKitDelegate.swift/purchase() 67

然后，我的paymentQueue(_:updatedTransactions:)被调用两次，首先是包含该一个事务的队列，然后第二次包含另外一个相同的事务：

2015-08-04 14:12:28.888 MyApp[33753:10941440] StoreKitDelegate instance <MyApp.StoreKitDelegate: 0x608000006fe0>
    payment queue <SKPaymentQueue: 0x608000006fd0>
    with transactions:
        <SKPaymentTransaction: 0x6080000032d0>
     --> StoreKitDelegate.swift/paymentQueue(_:updatedTransactions:) 274

2015-08-04 14:12:28.888 MyApp[33753:10941440] transaction state Purchasing: <SKPaymentTransaction: 0x6080000032d0>
    StoreKitDelegate instance <MyApp.StoreKitDelegate: 0x608000006fe0> --> StoreKitDelegate.swift/paymentQueue(_:updatedTransactions:) 282

2015-08-04 14:12:28.889 MyApp[33753:10941440] StoreKitDelegate instance <MyApp.StoreKitDelegate: 0x608000006fe0>
    payment queue <SKPaymentQueue: 0x608000006fd0>
    with transactions:
        <SKPaymentTransaction: 0x6080000032d0>
        <SKPaymentTransaction: 0x610000000f20>
     --> StoreKitDelegate.swift/paymentQueue(_:updatedTransactions:) 274

2015-08-04 14:12:28.889 MyApp[33753:10941440] transaction state Purchasing: <SKPaymentTransaction: 0x610000000f20>
    StoreKitDelegate instance <MyApp.StoreKitDelegate: 0x608000006fe0> --> StoreKitDelegate.swift/paymentQueue(_:updatedTransactions:) 282

当我取消交易并再次调用paymentQueue(_:updatedTransactions:)时，队列现在包含三个交易！

2015-08-04 14:13:38.128 MyApp[33753:10943465] StoreKitDelegate instance <MyApp.StoreKitDelegate: 0x608000006fe0>
    payment queue <SKPaymentQueue: 0x608000006fd0>
    with transactions:
        <SKPaymentTransaction: 0x6080000032d0>
        <SKPaymentTransaction: 0x610000000f20>
        <SKPaymentTransaction: 0x608000003200>
     --> StoreKitDelegate.swift/paymentQueue(_:updatedTransactions:) 274

2015-08-04 14:13:38.128 MyApp[33753:10943465] transaction state Failed: <SKPaymentTransaction: 0x608000003200>
    StoreKitDelegate instance <MyApp.StoreKitDelegate: 0x608000006fe0> --> StoreKitDelegate.swift/paymentQueue(_:updatedTransactions:) 288

请注意，每次都引用相同的委托对象。队列也是如此。所以问题不在于我正在注册多个代表等......

我得到的唯一领先是，工具付款后检测到StoreKit小泄漏：

Leaked Object   #   Address Size    Responsible Library Responsible Frame
OS_dispatch_queue   1   0x7fa81205db30  128 Bytes   StoreKit    __47-[SKProductsRequest issueRequestForIdentifier:]_block_invoke_2
Malloc 32 Bytes 1   0x7fa8105da530  32 Bytes    StoreKit    __47-[SKProductsRequest issueRequestForIdentifier:]_block_invoke_2

......交易取消后再次：

Leaked Object   #   Address Size    Responsible Library Responsible Frame
SKMutablePayment    1   0x7fa812077ad0  16 Bytes    StoreKit    -[SKPaymentTransaction initWithDictionary:]
SKPaymentInternal   1   0x7fa812054e90  48 Bytes    StoreKit    -[SKPayment init]
__NSCFString    1   0x7fa812009980  64 Bytes    Foundation  _getStringAtMarker

存在一个问题（Multiple SKPaymentTransaction），但是没有足够的问题可以判断问题是否相同，也没有解决问题的答案（除了通常的“你忘记完成了交易“）。

非常感谢任何帮助或见解。
