cocos2d in xcode communicate to a node.js server service via objective-C library called socket.io

I use xcode 4.6.1 cocos2d 2.x, ios sdk 6.1 , iphone 6.1 simulator.

I want to communicate from objective-c to server by node.js with socket.io.

so, I tried objective-c library called socket.io "socket.IO-objc"

https://github.com/pkyeck/socket.IO-objc

i succeeded a example "SocketTesterARC" in socket.IO-objc to communicate with server "node.js with socket.io".

SocketTesterARC :

(void) viewDidLoad {
   [super viewDidLoad];
   socketIO = [[SocketIO alloc] initWithDelegate:self];
   [socketIO connectToHost:@"localhost" onPort:8888];
   [socketIO sendEvent:@"join" withData:@"first room"];
   [socketIO sendMessage:@"hihihi"];
}

so, i applied "socket.io" library to new cocos2d project. i copied from example "SocketTesterARC"'s code to new cocos2d project.

but, error and not process!
