我在控制台中收到此错误:

[Purchases] - INFO: There is no singleton instance. Make sure you configure Purchases before trying to get the default instance.
*** Assertion failure in +[RCCommonFunctionality getPurchaserInfoWithCompletionBlock:], RCCommonFunctionality.m:118

但是,这是一个间歇性问题(即:并非总是会发生)。实际上,我已经在启动时设置了Purchases实例(即:在用户通过身份验证并获得UID之后立即):

 await Purchases.setDebugLogsEnabled(isDebugEnabled);
 await Purchases.setup(kRevenueCatApiKey, appUserId: uid);

有什么我想念的吗? (但大多数情况下都有效)

1 个答案:

答案 0 :(得分:1)

我发现了问题。因此,每当调用getPurchaserInfo时,但是如果Purchaser.setup尚未完成处理,则它将触发此异常。感谢上面@Cesar的评论。

就我而言,我发现问题是因为:

  • 我有两个Bloc分别处理IAP和业务逻辑。
  • 用户通过身份验证后,IAP会立即调用Purchases.setup。然后在主屏幕上,业务逻辑将通过执行getPurchaserInfo与服务器一起检查本地数据的有效性。
  • 当互联网连接不佳并且getPurchaserInfo完成处理之前,Purchases.setup被业务逻辑组触发时,就会出现问题。

因此,我要做的解决方案是确保一旦用Purchases.setup完成IAP组后,业务逻辑组就开始初始化。例如将它们放在等待每个进程的异步函数中。
