title: Launching Viber app via URL scheme on iOS
body: <p>I'm making an iOS app which can open Viber app and automatically call a person or go to chat window with the person. Is there any url scheme for Viber to do that such as:</p>
  
  <pre><code>viber://tel:&lt;phone_number&gt;
  viber://chat:&lt;phone_number&gt;
  </code></pre>
  
  <p>I followed <a href="https://stackoverflow.com/questions/16447148/how-to-start-viber-call-from-an-android-app">this</a> link but it's for Android.</p>
