iPhone 应用程序 : In App Purchase

Question

在应用内购买的 iPhone 应用中:SKPaymentTransactionStateRestored: 何时被调用？

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
    for (SKPaymentTransaction *transaction in transactions) {
      switch (transaction.transactionState) {
      case SKPaymentTransactionStateRestored:
        [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
        break;
      }
    }
}

以及如何从 apple 获得应用已成功购买的确认意味着我想在 NSlog 中打印该信息。

我应该为此写什么？

Answer 1

就我而言，transactions仅当 Apple 将 updatedTransactions 状态响应为 SKPaymentTransactionStateRestored 时才购买成功或 SKPaymentTransactionStatePurchased .
