监控到网络切换,调用OnNetworkChange()无效 #409

Closed HalfAnApple closed 6 years ago

HalfAnApple commented 6 years ago

https://github.com/Tencent/mars/blob/1db39d513c108fddb53a272f321fa58713ce5dc4/samples/iOS/iOSDemo/Bussiness/NetworkService.mm#L178-L184 使用samples/iOSDemo里的处理，由WiFi切换到4G网络，网络状态改变回调调用了OnNetworkChange(),但在此之后发送cgi没回应，几分钟后日志提示 task socket close,改变网络前cgi req是ok的，这里应该怎么处理？重建mars么？

以下Mars日志

看日志,调用 OnNetworkChange, 390][-> OnNetworkChange 函数之后，没有出来，应该卡在什么位置了。关联源码调试下 看卡死在什么地方了
