如何在ios中获取可更新的应用内产品的最新收货信息，以及如何检查收货是否过期？我的代码是： -获取收据

            -(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions
            {
                hide_HUD
                SKPaymentTransaction *transaction = transactions.lastObject;
                switch (transaction.transactionState) {
                    case SKPaymentTransactionStatePurchased:
                    {
                        [[SKPaymentQueue defaultQueue]finishTransaction:transaction];
                        NSLog(@"Order id ======>> %@",transaction.transactionIdentifier);
                        NSData *recData = [NSData dataWithContentsOfURL:[[NSBundle mainBundle] appStoreReceiptURL]];
                        NSString* receiptString = [[NSString alloc] initWithData:recData encoding:NSUTF8StringEncoding];

                        [self getReceiptFromAppStore:recData Transaction:transaction isBackground:NO];
                        break;
                    }

                    case SKPaymentTransactionStateFailed:
                        NSLog(@"Purchase failed ");
                        break;

                    case SKPaymentTransactionStateRestored:
                        [[SKPaymentQueue defaultQueue]finishTransaction:transaction];
                        break;

                    default:
                        //NSLog(@"Purchase failed ");
                        break;
                }
            }

                                       else{
                                           NSLog(@"%@",error);
                                       }
                                   }
                               }];
    }

我有收据，但我不知道如何从收据中获取数据以及如何使用它来防止用户进入应用程序的主页。

请仔细阅读收据字段，您将获得所有信息，例如到期，被苹果公司取消，帐单信息，取消等。

您必须访问 latest_receipt_info 数组中的最新对象，并检查字段 expires_date

订阅的到期日期，表示自1970年1月1日格林威治标准时间00:00:00以来的毫秒数。

ASN.1字段类型1708

ASN.1字段值IA5STRING，解释为RFC 3339日期

JSON字段名称expires_date

JSON字段值字符串，解释为RFC 3339日期

此密钥仅在自动续订的订阅收据中显示。使用此值来标识订阅将续订或到期的日期，以确定客户是否应有权访问内容或服务。验证最新收据后，如果最新续订交易的订阅到期日期是过去的日期，则可以安全地假定订阅已过期。
