title: Facebook SDK: app not registered as a URL Scheme
body: <p>I am using the <code>Facebook SDK</code> found <a href="http://components.xamarin.com/view/facebookios" rel="noreferrer">here</a>, and am trying the sample that is provided (in the folder <code>FacebookiOSSample</code>).</p>
  
  <p>If I simply replace the <code>AppId</code> here with my specific <code>AppId</code>, then I can no longer Share. (I replaced it in both the <code>AppDelegate</code> file and the <code>info.plist</code> file). I now receive the following error:</p>
  
  <blockquote>
    <p>FBSDKLog: Invalid use of FBAppCall, fb**** is not registered as a URL
    Scheme. Did you set 'FacebookUrlSchemeSuffix' in your plist?</p>
  </blockquote>
  
  <p>Otherwise this works fine with the sample's original <code>AppId</code> which points to something named <code>IFaceTouch</code>.</p>
  
  <p>What could be wrong with the setup of my app, how do I register my <code>AppId</code>?</p>
