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

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

                    default:

                                         he/she unsubscribe for that plan and after 1 month (on 22-2-2017),  
                                         if he/she open my app , he should not get   
                                         redirected to my app’s home page.
                                         */
                                       }
                                       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转到应用程序的主页。

请仔细阅读收据字段，您将获得所有信息，如过期、被苹果取消、账单信息、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，以自 1970 年 1 月 1 日以来的毫秒数表示，00:00:00 GMT。

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

此密钥仅适用于自动续订订阅收据。使用此值来标识订阅续订或过期的日期，以确定客户是否应该访问内容或服务。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，则可以安全地假设订阅已过期。
