title: Implementing UIActivity subclass for Facebook Messenger iPhone App?
body: <p>Hello I'm implementing different ways in my project to share some TEXT to other Chat Applications, such as: Whatsapp, Line and WeChat.</p>
  <p>I have no problem to implement this UIActivity subclass using following libs:</p>
  <ul>
  <li>Whatsapp (<a href="https://github.com/jberlana/JBWhatsAppActivity" rel="nofollow noreferrer">https://github.com/jberlana/JBWhatsAppActivity</a>)</li>
  <li>Line (<a href="https://github.com/OopsMouse/LINEActivity" rel="nofollow noreferrer">https://github.com/OopsMouse/LINEActivity</a>)</li>
  <li>WeChat (<a href="https://github.com/iDay/WeixinActivity" rel="nofollow noreferrer">https://github.com/iDay/WeixinActivity</a>)</li>
  </ul>
  <p>I realise all these Apps has internal URI protocol to communicate with them from my application:</p>
  <blockquote>
  <p>whatsapp://send?text=SAMPLE_TEXT</p>
  <p>line://msg/text/SAMPLE_TEXT</p>
  </blockquote>
  <p>Anyone knows the way to connect to Facebook Messenger iPhone App to share some text, at least?</p>
