Ios 获取用于在Swift中恢复应用内购买的已购买产品ID列表

我正在Swift中创建一个应用程序，其中包含应用程序内购买列表。我试图做的是获取/检索“已购买”产品标识符的列表

func productsRequest(request: SKProductsRequest!, didReceiveResponse response: SKProductsResponse!) {

}

例如，在上述方法中，我们可以获得可用产品的列表。我不想获取该列表，而是想获取已购买产品ID的列表。然后我将循环浏览该列表并启用这些产品的所有功能

---

有没有办法得到这份名单？或者通过其他方式获得该列表？

问题和代码中的信息太少。我建议你检查一下我刚才回答的问题：

它包含工作IAP代码和一些提示。我希望这对你有帮助

以下是完整的IAP代码：
