The reason you're seeing the error is because as soon as you receive the
response in your client, you're printing it and terminating the application
but the server is expecting a response (even though the method has a void
return value). I suspect the reason it works when you use
performSelectorWithDelay: is that the runtime knows that no response is
expected and so the message is sent asynchronously (i.e. as if you'd
specified oneway).
To fix it, add the oneway qualifier to your setAnswerText: method.
I think it would also be prudent to make sure that the client shuts down
gracefully, i.e. call [connection invalidate] at least.
You might want to go through your other methods and consider whether the
oneway qualifier should apply. You could do the same for "bycopy".
