How to send a string to a UDP socket in iOS7?

Question

I am trying to send a simple string on top of UDP in my iOS7 application to a known IP address and cannot find a simple explanation and sample code on how to do this. There's a lot about TCP, but not about UDP, and in my case it should be UDP.
