chatClient is a delightful chat client written for iOS. It's built on top of NSStream. For example, here's how to connect to the server:

-(void)initNetworkCommunication{
    CFReadStreamRef *readStream;
    CFWriteStreamRef *writeStream;
    CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"home.unname.eu", 1234, &readStream, &writeStream);
    inputStream=(NSInputStream *)readStream;
    outputStream=(NSOutputStream *)writeStream;
    [inputStream setDelegate:self];
    [outputStream setDelegate:self];
    //mi creo il ciclo che mi permette di controllare se ci sono dati da ricevere o da inviare, per avere le notifiche
    [inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
    [outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
    [inputStream open];
    [outputStream open];
}

How To Get Started

• Download chatClient and try to run the iPhone app
• To change the server or the port edit the method initWithNetworkCommunication in the ViewController.m file
• Insert a nickname
• Enjoy!
