在应用内购买：“恢复”已购买但尚未完成的交易 [英] In app Purchase: "Restore" a transaction that has been purchased but not completed

问题描述

如果他/她注册了可自动续订的订阅，我有一个为用户注册数据库的应用。

I've got an app that register a database for the user if he/she signs up for a auto-renewable subscription.

如果用户已完成购买并且应用程序崩溃或服务器处于脱机状态，因此用户无法注册数据库。用户需要以后能够注册数据库。

If user have made the purchase and the app crash or server is offline so user is not able to register the database. User need to be able to register the database later.

所以问题是如何恢复未调用此事务的交易

So question is how do i "restore" a transaction that haven't called this

[[SKPaymentQueue defaultQueue] finishTransaction: transaction]; 

如果我重新启动应用程序并打印出来，我将获得一个空数组。

If i restart the app and prints this i will get an empty array.

[[SKPaymentQueue defaultQueue] transactions];

推荐答案

您无需做任何事情。如果您在应用程序关闭之前没有机会调用 -finishTransaction：，那么下次您将自己添加为观察者时，您将再次传递该事务付款队列。

You don't have to do anything. If you didn't get a chance to call -finishTransaction: before the app closed, then you'll be passed the transaction again next time you add yourself as an observer of the payment queue.
