title: MQTT client for ios
body: <p>I am developing an app for IOS and need MQTT client, I searched and there are similar questions asking which client to use for iOS, paho c client seems to be popular choice, but some people are suggesting that apple doesn't approve c clients for communication stuff. i have 2 questions.</p>
  
  <p>1) which is most reliable/mature/complete MQTT client lib for iOS.</p>
  
  <p>2) is it approved by apple and they will accept app that uses it.</p>
  
  <p>I would prefer native objective-c libraries if they are available.</p>
