开发iPhone应用程序时，restoreCompletedTransactions遇到了一些麻烦。在沙盒环境中工作时，会出现下面列出的所有问题。该应用尚未销售。它是使用在模拟器5.0和5.1中运行的Xcode 4.3.2开发的。我遇到的问题是：
每次启动应用程序并放置对addTransactionObserver的调用时，都会通过购买交易调用updatedTransactions。在每个回调中，我的代码都调用finishTransaction：来完成购买，但是，每次我启动该应用程序时，都会一直发生此问题。确认完全相同的购买。
调用[[SKPaymentQueue defaultQueue] restoreCompletedTransactions]不会列出该帐户购买的所有非消耗性物品。我有2笔非消耗性物品的购买，每次只有1笔退货。如果我尝试购买列表中缺少的物品，我将收到一条消息，指示该物品已被购买。列表中缺少的项目不是我遇到问题1（上面列出的）的项目。
在这一点上，我完全陷入困境。我的应用程序依靠AppStore返回有关非消耗品的信息，因为我们没有将此数据保存在自己的服务器中。但是，我们需要确保AppStoreKit返回所有已购买商品的列表。不只是一些。
这是我用来测试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];
}
最佳答案
您是否在尝试每次应用程序启动时调用restoreCompletedTransactions？如果您想要所有交易的清单，则可以提出一个SKProductsRequest
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productsSet];
productsRequest.delegate = self;
[productsRequest start];
如果您想获取completedTransactions而又不找回所有东西，请显示日志。
