fb-messenger-api url scheme for specific user
<p>We can open the facebook messenger using the url scheme:</p>

<pre><code>   @"fb-messenger-api://"
</code></pre>

<p>I get the user Id by doing <code>FBSDKGraphRequest</code>  <code>WithGraphPath:@"/me/friends"</code></p>

<p>and I get my friend id by <code>result[@"data"][@"id"]</code> which looks something like:</p>

<pre><code>1234565657686
</code></pre>

<p>and it didnt worked. It just opens the messenger, but not the conversation window of my friend.</p>

<p>This is how I Actually try to open messenger:</p>

<pre><code>NSString *customURL = @"fb-messenger-api://user/1234565657686";

    if ([[UIApplication sharedApplication]
         canOpenURL:[NSURL URLWithString:customURL]])
    {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:customURL]];
    }
</code></pre>

<p>How can I open the fb messenger's particular user conversation window by using url scheme ?</p>
