輸入のUIKit

クラスのViewController：のUIViewController {

var step : Int = 0 

@IBOutlet weak var CounterLabel: UILabel! 

@IBAction func tapButton(sender: AnyObject) { 
    step = step + 1 
    updateLabel() 
} 

@IBAction func longPressButton(sender: UILongPressGestureRecognizer) { 
    if sender.state == .Changed { 
     step = step + 1 
     updateLabel() 
    } 
} 
@IBAction func resetButton(sender: AnyObject) { 
    step = 0 
    updateLabel() 
} 

func updateLabel() { 
    CounterLabel.text = String(step) 
} 


override func viewDidLoad() {
