SLComposeViewController - Post a message and an image to Facebook

Update:
December 19, 2015 - The solution below no longer works. It seems that Facebook SDK is required.
January 15, 2016 - See this: Facebook SDK and Swift - Post a message and an image to Facebook

1. Create a UIButton and a UIImageView

2. Include an image file swift.png (or a photo) in the project

3. Write the code as below:

import UIKit

import Social

class ViewController: UIViewController {

    @IBOutlet weak var myImage: UIImageView!

    

    var myUIImage : UIImage!

    

    @IBAction func facebookButtonPressed(sender: UIButton) {

        if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) {

            var myFBController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)

            myFBController.setInitialText("Test http://studyswift.blogspot.com")

            myFBController.addImage(self.myUIImage)

            self.presentViewController(myFBController, animated: true, completion: nil)

        } else {

            let alertView = UIAlertView()

            alertView.message = "Please login to Facebook."

            alertView.addButtonWithTitle("OK")

            

            alertView.show()

        }

    }

    override func viewDidLoad() {

        super.viewDidLoad()

        

        myUIImage = UIImage(named: "swift.png")

        

        self.myImage.image = myUIImage

    }
