无法从Facebook加载图片

Question

我想从Facebook获取我的头像图片，我试过这样：

import UIKit
import FBSDKCoreKit
import FBSDKLoginKit
import FBSDKShareKit
import FBSDKMessengerShareKit

class HomeViewController: UIViewController {

    @IBOutlet var avatarImageView: UIImageView!
    var id = ""

    override func viewDidLoad() {
        super.viewDidLoad()

        addBackgroundImage()

        let accessToken = FBSDKAccessToken.currentAccessToken()
        if accessToken != nil {
            print(accessToken.tokenString)
        }

//        let req = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"email,name"], tokenString: accessToken.tokenString, version: nil, HTTPMethod: "GET")
//        req.startWithCompletionHandler({ (connection, result, error : NSError!) -> Void in
//            error == nil ? print("result \(result)") : print("error \(error)")
//        })

        returnUserData()

    }

    func returnUserProfileImage(accessToken: NSString)
    {
        var userID = accessToken as NSString
        var facebookProfileUrl = NSURL(string: "http://graph.facebook.com/\(userID)/picture?type=large")

        if let data = NSData(contentsOfURL: facebookProfileUrl!) {
            avatarImageView.image = UIImage(data: data)
        }

    }

    func returnUserData()
    {
        let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
        graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in

            if ((error) != nil)
            {
                // Process error
                print("Error: \(error)")
            }
            else
            {
                print("fetched user: \(result)")

                if let id: NSString = result.valueForKey("id") as? NSString {
                    print("ID is: \(id)")
                    self.returnUserProfileImage(id)
                } else {
                    print("ID es null")
                }


            }
        })
    }

    func addBackgroundImage() {
        UIGraphicsBeginImageContext(self.view.frame.size)
        UIImage(named: "blur_background")?.drawInRect(self.view.bounds)
        let image: UIImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        view.backgroundColor = UIColor(patternImage: image)
    }
}

但它说：
