Obj-C, Storekit restoreCompletedTransactions returns zero transactions?
提问by Jules
I'm having some problems restoring completed transactions.
我在恢复已完成的交易时遇到了一些问题。
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
I've added the observer mentioned in several examples, I've tried adding paymentQueueRestoreCompletedTransactionsFinishedand already have updatedTransactions. paymentQueueRestoreCompletedTransactionsFinishedsays I have zero transactions.
我已经添加了几个例子中提到的观察者，我已经尝试添加paymentQueueRestoreCompletedTransactionsFinished并且已经有updatedTransactions. paymentQueueRestoreCompletedTransactionsFinished说我有零交易。
I can buy a product and if I try to buy again, it stops me and says I've already bought the product, using this code.
我可以购买产品，如果我再次尝试购买，它会阻止我并说我已经使用此代码购买了该产品。
SKPayment *payment = [SKPayment paymentWithProductIdentifier:productIdentifier];
[[SKPaymentQueue defaultQueue] addPayment:payment];
I thought maybe I had a problem with my bundle identifier, but that seems fine and the buy wouldn't work if it wasn't.
我想也许我的捆绑标识符有问题，但这似乎很好，如果不是，购买将无法正常工作。
I have been trying this on the device as well as the simulator, but this has the same result. Also, it doesn't make a difference If I'm using UK or US store.
我一直在设备和模拟器上尝试这个，但结果相同。此外，如果我使用英国或美国商店，这也没什么区别。
I'm really grasping at straws to find out why this doesn't work for me ?
我真的很想知道为什么这对我不起作用？

try to do it like this and check the array count is it return zero also ?
尝试这样做并检查数组计数是否也返回零？
- (void) checkPurchasedItems
{
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}//You Call This Function
//Then this delegate Function Will be fired
- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
purchasedItemIDs = [[NSMutableArray alloc] init];
NSLog(@"received restored transactions: %i", queue.transactions.count);
for (SKPaymentTransaction *transaction in queue.transactions)
{
NSString *productID = transaction.payment.productIdentifier;
[purchasedItemIDs addObject:productID];
}
}
