首先在应用购买交易中工作不正常ios

Question

我正在尝试在我的Unity3d-IOS项目中添加app purhase。我使用Storekit。我正确地将应用程序购买添加到itunes帐户，我的代码也可以（在应用程序购买逻辑和代码中我的以前的项目工作正常）。但是，目前，我的应用内购买效果非常好，除了首次购买交易外

在应用程序购买的第一个中，系统在付款之前给我购买（在我点击确认之前）或交易没有进入正确的SKPaymentTransactionState以便我向Unity发送消息并获取我的购买（即使我付款并且itunes给我“成功购买”对话框，它也没有调用正确的购买方式）。

除了首次在应用内购买尝试中，所有应用内购买都是成功的并且效果很好。正如我所说，我在以前的项目中使用了相同的逻辑（完全可以）。

我可以错过什么？有人可以帮忙吗？

*正如您可能猜到的，我使用沙盒测试帐户。
