GCDAsyncSocketManager provides qiuick-to-use GCDAsyncSocket to build socket,it contains connect,disconnect,reconnect,beat,general request
GCDAsyncSocketManager提供快速使用GCDAsyncSocket来搭建socket，它包含了建连、断开、重连、心跳、通用请求
socket connect:
you can connect when app enter forground or ViewController view will appear
[[GCDAsyncSocketCommunicationManager sharedInstance] createSocketWithToken:@"your token" channel:@"your communication channel"];socket disconnect:
you can disconnect when app enter background
[[GCDAsyncSocketCommunicationManager sharedInstance] disconnectSocket];we provide a general interface to send request
type is the request type
body is the request body
callback is the request handle complete callback to app
- (void)socketWriteDataWithRequestType:(GACRequestType)type
requestBody:(nonnull NSDictionary *)body
completion:(nullable SocketDidReadBlock)callback;for example:
[[GCDAsyncSocketCommunicationManager sharedInstance] socketWriteDataWithRequestType:GACRequestType_GetConversationsList requestBody:requestBody completion:^(NSError * _Nullable error, id _Nullable data) {
// do something
if (error) {
} else {
}
}];
