class HomeViewController: UIViewController, UITextFieldDelegate
{
@IBOutlet var txt_field: UITextField!

    override func viewDidLoad()
    {
        super.viewDidLoad()
        self.title = "Home View Controller"
        txt_field = UITextField(frame: CGRect(x: 80, y: 300, width: 200, height: 30))
        txt_field.layer.borderColor = UIColor.blackColor().CGColor
