我正在执行“应用程序购买 - 消耗品”系统。在第一次，我可以正常购买，但是当我在下次尝试购买时，它不起作用。所以我换了一个测试用户，它也只能第一次购买。它显示“SK付款交易状态失败”，我该如何解决？我无法在应用程序购买中重新购买 - 消耗品
- (void)buyProduct:(int)myNumber{
SKPayment *payment = [SKPayment paymentWithProductIdentifier:[appDelegate.ArrayProductName objectAtIndex:myNumber]];
[[SKPaymentQueue defaultQueue] addPayment:payment];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
for (SKPaymentTransaction *transaction in transactions){
switch (transaction.transactionState) {
case SKPaymentTransactionStatePurchasing:
break;
case SKPaymentTransactionStatePurchased:
[self completeTransaction:transaction];
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
break;
case SKPaymentTransactionStateRestored:
[self restoreTransaction:transaction];
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
break;
case SKPaymentTransactionStateFailed:
if (transaction.error.code != SKErrorPaymentCancelled){
NSLog(@"An error encounterd : %@",transaction.error.code);
}
break;

}
}
