Swift: Versuchen, Facebook zu verwenden Öffnen Sie Graph Stories

Question

Ich versuche, Facebooks Open Graph Stories-Funktion in Swift zu verwenden, um bei jeder Überprüfung eines Standorts auf der Timeline eines Benutzers zu posten. Aber jeder Share-Dialog öffnet sich, ich bekomme immer this Fehler.

Ich folgte den Facebook Docs beim Erstellen eines Objekts, und dann eine Aktion, und dann schließlich Inhalt. Aber es scheint nicht zu funktionieren.

Unten ist mein Code:

class rateViewController: UIViewController, FBSDKSharingDelegate{ 

@IBOutlet weak var card: UIView! 
@IBOutlet weak var cardBackground: UIView! 

// VARIABLES 

// CREATE THE OPENGRAPH OBJECT 
var openGraphTest = FBSDKShareOpenGraphObject.init(properties: [ 

    "place:location:latitude": "51.043553", 
    "place:location:longitude":"-114.078141", 
    "og:type" : "place", 
    "og:title" : "Rating" 
]) 

// CREATE AN ACTION 
var action = FBSDKShareOpenGraphAction.init() 

// CREATE CONTENT 
let content = FBSDKShareOpenGraphContent.init() 

override func viewDidLoad() { 
    super.viewDidLoad() 

    action.actionType = "og.likes" 
    action.setObject(openGraphTest, forKey: "place") 

    content.action = action 
    content.previewPropertyName = "place" 

    // Do any additional setup after loading the view. 
} 

@IBAction func panCard(_ sender: UIPanGestureRecognizer) { 

    let card = sender.view! // Represents card UIView 
    let point = sender.translation(in: view) // How far you moved your finger, when touching view and dragging 

    card.center = CGPoint(x:(view.center.x + point.x), y: (view.center.y + point.y)) 

    // RECENTERING THE CARD AFTER USER REMOVES FINGER FROM SCREEN 

    if(sender.state == UIGestureRecognizerState.ended){ 

     if(card.center.x < 75){ 

      // MOVE CARD TO THE LEFT SIDE OF SCREEN 
      UIView.animate(withDuration: 0.3, animations: { 

       card.center = CGPoint(x: self.cardBackground.center.x - 300, y: self.cardBackground.center.y + 75) 
       card.alpha = 0 
      }) 
      return 
     } 
     else if(card.center.x > (view.frame.width - 75)){ 

      // MOVE CARD TO THE RIGHT SIDE OF SCREEN 
      UIView.animate(withDuration: 0.3, animations: { 

       card.center = CGPoint(x: self.cardBackground.center.x + 300, y: self.cardBackground.center.y + 75) 
       card.alpha = 0 
      }) 
      // SHOW THE FACEBOOK SHARE DIALOG 

      try FBSDKShareDialog.show(from: self, with: content, delegate: self) 
      return 
     } 
     UIView.animate(withDuration: 0.2) { 
      card.center = self.cardBackground.center 
     } 
    } 
} 

@IBAction func likeButton(_ sender: UIButton) { 

    // MOVE CARD TO THE RIGHT SIDE OF SCREEN 

    UIView.animate(withDuration: 0.3, animations: { 

     self.card.center = CGPoint(x: self.cardBackground.center.x + 300, y: self.cardBackground.center.y + 75) 
     self.card.alpha = 0 
    }) 

} 

@IBAction func dislikeButton(_ sender: UIButton) { 

    // MOVE CARD TO LEFT SIDE OF SCREEN 

    UIView.animate(withDuration: 0.3, animations: { 

     self.card.center = CGPoint(x: self.cardBackground.center.x - 300, y: self.cardBackground.center.y + 75) 
     self.card.alpha = 0 
    }) 
}

Nach Facebook in Kontakt und mit einem ihrer Entwickler sprechen, anfangs hatte ich angenommen, dass es einen Fehler in der API war, aber es stellt sich heraus, dass ich es tat falsch. Unten ist mein Code:

// CREATE THE OPEN GRAPH OBJECT 

    let properties : [AnyHashable : Any] = [ 
     "fb:ap_id":"APP ID FOUND ON FACEBOOK APP DASHBOARD", 
     "og:type":"object", 
     "og:title": "Some Title", 
    ] 

    let object : FBSDKShareOpenGraphObject = FBSDKShareOpenGraphObject(properties: properties) 

    // CREATE AN ACTION 

    action.actionType = "og.likes" 
    action.setObject(object, forKey:"object") 

    // CREATE CONTENT MODEL 

    content.action = action 
    content.previewPropertyName = "object" 

    // SETTING UP THE SHARE DIALOG 

    shareDialog.fromViewController = self 
    shareDialog.shareContent = content 

    // SHOW THE SHARE DIALOG 
    if(shareDialog.canShow()){ 
     shareDialog.show() 
    } 
    else{ 
     print("Unable to show dialog") 
    } 

    do{ 
     try shareDialog.validate() 
     } 
    catch{ 
     print("Invalid") 
     }
