iOS IAP paymentQueue : updatedTransactions

Question

SKPaymentTransactionObserver.paymentQueue : updatedTransactions는 트랜잭션 배열을 반환합니다. 지불 할 때 지불 한 거래는 어떻게 알 수 있습니까? 결제 할 때 항상 하나의 거래가 반환됩니까?

한편이 옵저버 함수는 트랜잭션을 복원 할 때도 호출됩니다. 따라서 updatedTransactions를 처리하는 가장 좋은 방법은 무엇입니까?

트랜잭션 루프를 반복하고 각 트랜잭션을 확인하십시오.
