问题描述
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)
解决方法
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。
