How do I read data using CocoaAsyncSocket?

Question

I have created a TCP Socket connection in my appDelegate didFinishLaunchingWithOptions method. That was the easy part, and I have successfully connect

This should work:

- (void)onSocket:(AsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag
{
    NSData *strData = [data subdataWithRange:NSMakeRange(0, [data length])];
    NSString *msg = [[NSString alloc] initWithData:strData encoding:NSUTF8StringEncoding];
    if(msg)
    {
        NSLog(@"RX:%@",msg);
    }
}

You should also implement some other delegate methods, for example:

- (void)onSocket:(AsyncSocket *)sock willDisconnectWithError:(NSError *)err
{
    NSLog(@"error - disconnecting");
    //you'd probably want to start reconnecting procedure here...
}

- (void)onSocketDidDisconnect:(AsyncSocket *)sock
{
    NSLog(@"disconnected");
}

- (void)onSocket:(AsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port
{
    NSLog(@"connected");
}

EDIT: if memory serves me right there is some documentation and also some examples available with the library.
