Facebook graph api. Get photos from albums

Question

Please help me to make a correct request to Facebook api. Now i've got:

https://graph.facebook.com/me/albums?fields=photos

As the result I get very big Json with a lot of unnecessary info. I tried to do something like this:

https://graph.facebook.com/me/albums?fields=photos?fields=source,name,id

or like this:

https://graph.facebook.com/me/albums?fields=photos&fields=source,name,id

But graph api explorer, returned the same big response, or i caught an error. Any ideas how to do more compact response with only necessary info?

Answer 1

GETTING ALBUM_ID

    if((FBSDKAccessToken.current()) != nil)
    {
        FBSDKGraphRequest(graphPath: "me/albums", parameters: ["fields" : "id"], httpMethod: "GET").start(completionHandler: { (connection, result, error) -> Void in
            if (error == nil)
            {
                let data:[String:AnyObject] = result as! [String : AnyObject]
                self.arrdata = data["data"]?.value(forKey: "id") as! [String ]
            }
        })
    }

with above code you will get album_Id and then with that id we can get image like this : GETTING IMAGES FROM ALBUM_ID

    FBSDKGraphRequest(graphPath: "\(album_Id)/photos", parameters: ["fields": "source"], httpMethod: "GET").start(completionHandler: { (connection, result1, error) -> Void in
       if (error == nil)
       {
           let data1:[String:AnyObject] = result1 as! [String : AnyObject]
           let arrdata:[String] = data1["data"]?.value(forKey: "source") as! [String ]
           for item in arrdata
           {
               let url = NSURL(string: item )
               let imageData = NSData(contentsOf: url! as URL)
               let image = UIImage(data: imageData! as Data)
               self.imgArr.append(image!)
           }
        }
     })

Answer 2

for Swift 5

first get albums id like this

func getAlbumsData()
{

        GraphRequest.init(graphPath: "me", parameters: ["fields":"id,name,albums{name,picture}"]).start(completionHandler: { (connection, userResult, error) in

            if error != nil {

                print("error occured \(String(describing: error?.localizedDescription))")
            }
            else if userResult != nil {
                print("Login with FB is success")
                print()



                let fbResult:[String:AnyObject] = userResult as! [String : AnyObject]

                self.albumsPhotos = (fbResult["albums"] as! [String:AnyObject])["data"] as? [[String:AnyObject]]
                self.tblFbAlbums.reloadData()




            }
        })
    }

then get albums image with this method

func fetchalbumsPhotosWithID() {


        let graphRequest : GraphRequest  = GraphRequest(graphPath: "\(album_Id)/photos", parameters: ["fields": "source"] )

        graphRequest.start(completionHandler: { (connection, result, error) -> Void in

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

                let data =  result as! [String:Any]


            }
        })

    }

album_Id is a number you get from getAlbumsData()
