Swift / Facebook like button / how to confirm that the user already set like
<p>I'm using the following code:</p>

<pre><code>    let likeControl:FBSDKLikeControl = FBSDKLikeControl()
    likeControl.objectID = "geckoclubmuc"
    likeControl.likeControlStyle = FBSDKLikeControlStyle.BoxCount
    likeControl.frame = CGRectMake(58, 407, 200, 40)
    likeControl.likeControlHorizontalAlignment = .Left
    self.view.addSubview(likeControl)
</code></pre>

<p>The like button is displayed. After the user liked the page, it shows how many users like it. If the app restarts, the Like button is "reset".</p>

<p>How can I save that the user already did liked the page (and keep display the likes amount)?</p>

<p>Help is very appreciated.</p>
