ios - Domain=NSPOSIXErrorDomain Code=61 -

i'm trying connect between client(ios app) , server(node.js) using socketrocket , ws below.

ios(socketrocket):

nsurl *url = [nsurl urlwithstring:@"ws://localhost:8080"]; srwebsocket *_socket = [srwebsocket alloc] initwithurlrequest:[nsurlrequest requestwithurl:url]; _socket.delegate = self; [_socket open];  /* srwebsocketdelegate */ -(void)websocketdidopen:(srwebsocket*)websocket{     [websocket send:@"something"]; } -(void)websocket:(srwebsocket*)websocket didreceivemessage:(id)message{     nslog(@"didreceivemessage: %@",[message description]); } -(void)websocket:(srwebsocket*)websocket didfailwitherror:(nserror*)error{     nslog(@"the error: %@",error); } 

node.js(ws):

var websocketserver = require('ws').server var wss = new websocketserver({     host:'localhost',     port:8080 }); wss.on('connection',function(ws){     ws.on('message',function(message){         console.log('received: %s', message);         ws.send(message);     }); }); 

then, got message below:
