How to make an iOS 8 share extension that will have default text

Question

In my app there is text displayed in a label on screen.

I have a share button when pressed brings the UIActivityViewController but when you press the share extensions ex: Twitter, you get the compose view with nothing inside of it.

I want it that it puts the text from the label on the screen into the compose view.

I don't know how you did this but it would work well. suppose you put it on a action sheet :

let share = UIAlertAction(title: "Share my label!", style: .Default, handler: { action in
        let shareMessage = myLabel.text
        let itemsToShare = [shareMessage]

        let activityViewController = UIActivityViewController(activityItems: itemsToShare,
            applicationActivities: nil)

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

    })
