Swift: Get one line from an NSTextField

G'day,

I have created a simple Swift app with an NSTextField and a button. The NSTextField is preloaded with some text via the viewDidLoad method.

I want to double click and highlight a single line of text then read that line into a variable when the button is pressed. This should be straight forward but I cannot even get close and I can't find any other questions as simple as this one.

Can someone help?

import Cocoa

class ViewController: NSViewController {

    @IBOutlet weak var myTextField: NSTextField!


    @IBAction func readTheTextField(sender: AnyObject) {
        println("Read button pushed.")
        // I need some code in here.
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        myTextField.stringValue += "To be or not to be.\n"
        myTextField.stringValue += "That is the question.\n"
        myTextField.stringValue += "Whether tis nobler in the mind,\n"
        myTextField.stringValue += "to suffer the slings and arrows of outrageous fortune."
    }

    override var representedObject: AnyObject? {
        didSet {
        // Update the view, if already loaded.
        }
    }


}

Take a look at the NSScanner class, and specifically the method scanUpToCharactersFromSet. You'd give it a newline character, and have it scan one line at a time into another string.
