cocoa asyncudpsockets don't send bytestream

I have a little MAC OS X Application that should send a UDP Datagram to a server.

I want to use the cocoa asyncudpsockets (http://code.google.com/p/cocoaasyncsocket/) to do this, but i have the problem that i call the "sendData" method but nothing happens.

[socket sendData:[NSData dataWithBytes:stream length:length] 
          toHost:host 
            port:(uint16)port 
     withTimeout:5 
             tag:1];

stream is a Byte* contains the datagram host is a ip-address as NSString.

Can anybody help me?

Did you correctly set the delegate ?

[socket setDelegate:self];

Then :

[socket connectToHost:(NSString *)host
               onPort:(UInt16)port
          withTimeout:(NSTimeInterval)timeout
                error:(NSError **)errPtr];

Then in the delegate method :

- (void)socket:(GCDAsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port
{
    [sock writeData:[NSData dataWithBytes:stream length:length] withTimeout:TIMEOUT_NONE tag:TAG_HEADER];
}

Hope it will help ;-)
