Question

在开发iPhone应用程序时，我遇到了很多关于restoreCompletedTransactions的问题。在沙箱环境中工作时，会出现下面列出的所有问题。该应用尚未销售。它是在模拟器5.0和5.1中运行的Xcode 4.3.2开发的。我得到的问题是：

每次启动应用程序并调用addTransactionObserver时，都会调用updatedTransactions并购买一个事务。在每个回调中，我的代码调用finishTransaction：来完成购买，但每次启动应用程序时都会发生此问题。确认购买完全相同的商品。
调用[[SKPaymentQueue defaultQueue] restoreCompletedTransactions]不会列出随帐户购买的所有非消耗品。我有2次购买非消耗品，每次只返回1件。如果我尝试购买列表中缺少的项目，我将收到一条消息，表明该项目已被购买。列表中缺少的项目不是我遇到问题1（上面列出的）。

此时我完全卡住了。我的应用程序依赖于AppStore来返回非耗材的信息，因为我们没有将这些数据保存在我们自己的服务器中。但我们需要确保AppStoreKit返回包含所有购买项目的列表。不只是一些。

以下是我用来测试restoreCompletedTransactions的相关代码：

- (void) paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    NSLog(@"updatedTransactions started. -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ ");
    NSLog(@"Number of transactions received: %d.", [transactions count]);
    int count = 0;
    for (SKPaymentTransaction *trans in transactions)
{
    NSLog(@"Data for transaction %d: ", ++count);
    NSString *transId = [trans transactionIdentifier];
    switch ([trans transactionState])
    {
        case SKPaymentTransactionStatePurchasing:
            NSLog(@"Purchasing transaction: %@", transId);
            if (transId == nil)
            {
                NSLog(@"    Original transaction Id: %@", [[trans originalTransaction] transactionIdentifier]);
            }

            NSLog(@"     No action taken in update");
            break;
        case SKPaymentTransactionStateFailed:
            NSLog(@"Purchase transaction failed for transaction %@", transId);
            NSLog(@"     Error %d (%@)", [[trans error] code], [[trans error] localizedDescription]);
            NSLog(@"     Action Taken:  finish transaction.");
            [queue finishTransaction: trans];
            break;
        case SKPaymentTransactionStatePurchased:
            NSLog(@"Purchased transaction %@", transId);
            NSLog(@"     Purchased qty %d of  product %@", [[trans payment] quantity], [[trans payment] productIdentifier]);
            NSLog(@"     Action: called [queue finishTransaction:] to complete purchase");
            [queue finishTransaction: trans];
            break;
        case SKPaymentTransactionStateRestored:
        {
            SKPayment *paym = [trans payment];
            SKPaymentTransaction *origTrans = [trans originalTransaction];
            SKPayment *origPayment = [[trans originalTransaction] payment];
            NSLog(@"Transaction restored: %@ with original transaction %@", transId, [[trans originalTransaction] transactionIdentifier]);
            NSLog(@"     TRANSACTION DATA:");
            NSLog(@"           purchased %d of product %@ on %@.", 
                  [paym quantity], 
                  [paym productIdentifier], 
                  [[trans transactionDate] description]);

            NSLog(@"     ORIGINAL TRANSACTION DATA:");
            NSLog(@"           purchased %d of product %@ on %@.", 
                  [origPayment quantity], 
                  [origPayment productIdentifier], 
                  [[origTrans transactionDate] description]);

            NSLog(@"     No action taken.");
            break;
        }

        default:
            NSLog(@"Unexpected transaction state:  %d", [trans transactionState]);
            NSLog(@"     No action taken.");
            break;
    }
}

NSLog(@"");
NSLog(@"updatedTransactions ended. -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ ");
}

- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
NSLog(@"Restore completed transactions finished.");
NSLog(@"     Number of transactions in queue:  %d", [[queue transactions] count]);
for (SKPaymentTransaction *trans in [queue transactions])
{
    NSLog(@"          transaction id %@ for product %@.", [trans transactionIdentifier], [[trans payment] productIdentifier]);
    NSLog(@"          original transaction id: %@ for product %@.", [[trans originalTransaction] transactionIdentifier],
          [[[trans originalTransaction] payment]productIdentifier]);
    }
NSLog(@"");
}

// Method to restore transactions when user clicks button in application
- (void) onRestoreCompletedTransactions:(id)sender
{
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

Answer 1

每次应用程序启动时，您是否尝试调用restoreCompletedTransactions？如果您想要所有交易的列表，您将进行SKProductsRequest

 SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productsSet];
    productsRequest.delegate = self;
    [productsRequest start];

如果你想获得completedTransactions并且没有收回所有内容，请显示日志。

Answer 2

SKProductsRequest将返回SKProduct实例列表。 SKProduct类不会在我的阅读中购买信息。我想你确实想要使用restoreCompletedTransactions并获取SKPaymentTransaction实例的列表。也就是说，我在使用沙盒帐户时遇到了同样的问题。我找回了一份不完整的交易清单（48个中的23个）。但是，如果我选择购买已购买但未恢复的非消耗品，那么该商店是已购买的商品，并将发回该商品的恢复。

运气好吗？
