CocoaAsyncSocket 7.4.2 Description:
CocoaAsyncSocket supports TCP and UDP. The AsyncSocket class is for TCP, and the AsyncUdpSocket class is for UDP. Each class is described below. AsyncSocket is a TCP/IP socket networking library that wraps CFSocket and CFStream. It offers asynchronous operation, and a native Cocoa class complete with delegate support. AsyncUdpSocket is a UDP/IP socket networking library that wraps CFSocket. It works almost exactly like the TCP version, but is designed specifically for UDP.
