Networking with ios

Question

Hi,

I have an application that was written in Java and runs on the users machine. I now want to build an application on the iPhone which will communicate with my java app.

Can somebody point me in the right direction on how I can send and receive TCP packets with the iPhone, I want to of course be able to do that using wifi and 3G.

Thanks,

You use the NSStream classes. I've found it pretty easy to use.

See the SimpleNetworkStreams for an example.

One problem I found is that the iphone sdk does not include the NSStream method getStreamsToHost:port:inputStream:outputStream: which is what Mac OS examples use to open a NStream connection but there are lots of places that show you how to create your own like here.
