title: Share image to WhatsApp directly using url scheme
body: <p>I want to integrate <code>WhatsApp</code> sharing in my app but I don't want to use <code>UIDocumentInteractionController</code>. Is there any way to share image using <code>url scheme</code> ? like we share text using url scheme using following code below</p>
  
  <pre><code>var whatsappURL:NSURL?= NSURL(string: "whatsapp://send?text=Hello%2C%20World!")
  if (UIApplication.shared.canOpenURL(whatsappURL)) {    
          UIApplication.shared.openURL(whatsappURL) 
      }
  </code></pre>
