    let greetingLabel = UILabel()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        self.showGreetingButton.addTarget(self, action: "didTapButton:", forControlEvents: .TouchUpInside)
    }
    
    func didTapButton(button: UIButton) {
        let greeting = "Hello" + " " + self.person.firstName + " " + self.person.lastName
        self.greetingLabel.text = greeting
