Is there pub sub support in the iOS SDK or in any framework for iOS (in essence a wrapper for NSNotificationCenter, that would facilitate use and also add additional functionality)?

I find pub sub very helpful for designing mobile applications and on Android I use Otto and found it very helpful for sharing application events (such as when temperature gets updated from a web service). Searching online, I have found only one framework (bendytree ) and it does not seem very active (only two commits).

Is this already built into the SDK, or is there a standard library commonly used? (Or maybe nobody does pub-sub on iOS?)

Have you considered using a managed cloud services like Pusher or Realtime? They both implement publish/subscribe and have native iOS SDK's.

  • Thanks but that slightly different then what I'm looking for. Those services help with client to server communication. I am looking for a framework that works for in app communication. It gets very ugly if you have to use callbacks everywhere. – stevebot Jan 23 '15 at 18:01

Try following samples. It works perfectly for me. These links will give solution for publish subscribe which is the advanced concept for NSNotificationCenter.
