iOS: Launch app from facebook
<p>We currently have a custom url scheme that launches our app when the user browses to the page via mobile safari, however I have had zero success getting our app to launch when a link is clicked or view via Facebook's Messenger webview and I am not quite sure why.</p>

<p>I have tried setting the <code>target</code> attribute to <code>_blank</code> which seems to be the only suggestion I can find, however it does not work.</p>

<p>So to my question is, how can I get our ios app to launch from Facebook Messenger's Webview?</p>
