IOS SocketIO chat app issues, Node JS as backend - ios

Question

Friends
i am working on a chat application where there a function in backend like
client.on('mjmChatAddUser', function(user, room)
{
// Guest
if(user == null)
user = mjmChatCreateGuestName();
// Convert special characters to HTML entities
user = htmlEntities(user);
room = htmlEntities(room);
client.username = user;
client.room = room;
mjmChatUsernames.push(user);
client.join(room);
client.emit('mjmChatStatusUser', 'you have joined to '+ room +' room');
client.broadcast.to(room).emit('mjmChatStatusUser', user +' has joined to this room');
client.emit('mjmChatRooms', room);
io.sockets.to(room).emit('mjmChatUsers', mjmChatGetUsersRoom(room));
});
Now from ios side , I want to use ScoketIO to call this function , I have made connection to server but not enable to call this function , this what i am doing , is it right way , please guide me
- (void) viewDidLoad
{
[super viewDidLoad];
// create socket.io client instance
socketIO = [[SocketIO alloc] initWithDelegate:self];
// you can update the resource name of the handshake URL
// see https://github.com/pkyeck/socket.IO-objc/pull/80
// [socketIO setResourceName:#"whatever"];
// if you want to use https instead of http
// socketIO.useSecure = YES;
// pass cookie(s) to handshake endpoint (e.g. for auth)
NSDictionary *properties = [NSDictionary dictionaryWithObjectsAndKeys:
#"localhost", NSHTTPCookieDomain,
#"/", NSHTTPCookiePath,
#"auth", NSHTTPCookieName,
#"56cdea636acdf132", NSHTTPCookieValue,
nil];
NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:properties];
NSArray *cookies = [NSArray arrayWithObjects:cookie, nil];
socketIO.cookies = cookies;
// connect to the socket.io server that is running locally at port 3000
[socketIO connectToHost:#"MY SERVER" onPort:3000];
}
# pragma mark -
# pragma mark socket.IO-objc delegate methods
- (void) socketIODidConnect:(SocketIO *)socket
{
NSLog(#"socket.io connected.");
NSMutableDictionary *dict2 = [NSMutableDictionary dictionary];
[dict2 setObject:#"demo1" forKey:#"user"];
[dict2 setObject:#"php" forKey:#"room"];
[socketIO sendEvent:#"mjmChatAddUser" withData:#{#"Abc":#"php"}];
}
- (void) socketIO:(SocketIO *)socket didReceiveEvent:(SocketIOPacket *)packet
{
NSLog(#"didReceiveEvent()");
// test acknowledge
SocketIOCallback cb = ^(id argsData) {
NSDictionary *response = argsData;
// do something with response
NSLog(#"ack arrived: %#", response);
// test forced disconnect
[socketIO disconnectForced];
};
[socketIO sendMessage:#"hello back!" withAcknowledge:cb];
}
- (void) socketIO:(SocketIO *)socket onError:(NSError *)error
{
if ([error code] == SocketIOUnauthorized) {
NSLog(#"not authorized");
} else {
NSLog(#"onError() %#", error);
}
}
- (void) socketIODidDisconnect:(SocketIO *)socket disconnectedWithError:(NSError *)error
{
NSLog(#"socket.io disconnected. did error occur? %#", error);
}
