This is a simple STOMP client based on
- an initial implementation (StompService) from Scott Raymond sco@scottraymond.net (see http://gist.github.com/72935)
- and AsynSocket: http://code.google.com/p/cocoaasyncsocket/
http://dev.coravy.com/wiki/display/OpenSource/Stomp+client+for+Objective-C
Add AsynSocket.{h,m} and CRVStompClient.{h,m} to your project.
