应用内购买恢复过程iOS 9

Question

如果我没有使用 paymentQueueRestoreCompletedTransactionsFinished 方法但在 paymentQueue中使用已恢复的交易状态（队列：SKPaymentQueue，updatedTransactions Transactions：[SKPaymentTransaction]）喜欢这里：

1

paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
        print("add paymnet")

        for transaction:AnyObject in transactions {
            let trans = transaction as! SKPaymentTransaction
            print(trans.error)

            switch trans.transactionState {

            case .Purchased. Restored:
...

and 

...
    @IBAction func RestorePurchases(sender: UIButton) {
        SKPaymentQueue.defaultQueue().addTransactionObserver(self)
        SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
    }

或者我将使用 paymentQueueRestoreCompletedTransactionsFinished 方法，但在 paymentQueue中的.Restored状态（队列：SKPaymentQueue，updatedTransactions Transactions：[SKPaymentTransaction]）我将使用这里的刹车操作员：

2

func paymentQueueRestoreCompletedTransactionsFinished(queue: SKPaymentQueue) {
//restored code here
}

//and 

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

        for transaction:AnyObject in transactions {
            let trans = transaction as! SKPaymentTransaction
            print(trans.error)

            switch trans.transactionState {

            case .Purchased:
...
            case .Restored:
             break
...

//and 

...
    @IBAction func RestorePurchases(sender: UIButton) {
        SKPaymentQueue.defaultQueue().addTransactionObserver(self)
        SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
    }

任何帮助将不胜感激！

PS

恢复过程中消耗品和非消耗品购买的代码是否有任何差异？
