如何在iOS7中的UDP套接字中发送字符串？

Question

I am trying to send a simple string over UDP in my iOS7 app to a known IP and could not find a simple explanation and sample code on how to do that. There is plenty out there about TCP but not so much about UDP and it has to be UDP in my case.

Answer 1

You could use https://github.com/robbiehanson/CocoaAsyncSocket , which is an Objective-C wrapper for TCP and UDP connections. It also contains sample code for TCP and UPD clients and servers.

Answer 2

you could use this wrapper-less simple gist . Happy networking.
