使用CXEndCallAction请求事务时出错

标签： voip ios10 callkit

在使用CXEndCallAction请求CXTransaction时，事务失败并显示错误代码 错误域= com.apple.CallKit.error.requesttransaction Code = 4“（null）”

我能够成功制作CXStartCallAction。有谁知道这个错误意味着什么？

CallKit的错误代码在<CallKit/CXError.h>中定义，而在iOS 10 Seed 4中，域com.apple.CallKit.error.requesttransaction的错误代码4定义为：

CXErrorCodeRequestTransactionErrorUnknownCallUUID = 4,

这表示请求的CXEndCallAction的调用UUID与已知调用不对应。我建议确认CXEndCallAction上设置的UUID与现有呼叫匹配。

如果您使用

CXStartCallAction

使用CXCallUpdate更新action.uuid您必须使用action.callUUID，而不是unknownCallUUID。

稍后在通话结束时导致func provider(_ provider: CXProvider, perform action: CXEndCallAction) 错误。在这种情况下
