Getting username and profile picture from Facebook iOS 7

Question

I have read a lot of tutorials about getting information from Facebook, but I have failed so far. I just want to get username and profile picture from Facebook.

Answer 1

This is the code for Facebook SDK 4 and Swift:

if FBSDKAccessToken.currentAccessToken() != nil {
    FBSDKGraphRequest(graphPath: "me", parameters: nil).startWithCompletionHandler({ (connection, result, error) -> Void in
        println("This logged in user: \(result)")
        if error == nil{
            if let dict = result as? Dictionary{
                println("This is dictionary of user infor getting from facebook:")
                println(dict)
            }
        }
    })
}

UPDATE TO ANSWER QUESTIONS:

To download public profile image, you get the facebook ID from the dictionary:

let facebookID:NSString = dict["id"] as AnyObject? as NSString

And then call a request to graph API for profile image using the facebook ID:

let pictureURL = "https://graph.facebook.com/\(fbUserId)/picture?type=large&return_ssl_resources=1"

Sample code:

    let pictureURL = "https://graph.facebook.com/\(fbUserId)/picture?type=large&return_ssl_resources=1"
    //
    var URLRequest = NSURL(string: pictureURL)
    var URLRequestNeeded = NSURLRequest(URL: URLRequest!)
    println(pictureURL)



    NSURLConnection.sendAsynchronousRequest(URLRequestNeeded, queue: NSOperationQueue.mainQueue(), completionHandler: {(response: NSURLResponse!,data: NSData!, error: NSError!) -> Void in
        if error == nil {
            //data is the data of profile image you need. Just create UIImage from it

        }
        else {
            println("Error: \(error)")
        }
    })
