   override func viewDidLoad() {
     super.viewDidLoad()
     // Do any additional setup after loading the view.
     self.signatureState()
   }

   /// Signature State by CallBack
   private func signatureState() {
     self.drawSignatureView.currentTouchState = { [weak self] (touchState) in
       switch touchState {
       case .began:
         print("began")
       case .moved:
         print("moved")

     self.captureSignatureImageView.image = nil
     self.drawSignatureView.erase()
   }

   /// Capture Siganture
   @IBAction func captureSignature(_ sender: UIButton) {

     self.drawSignatureView.captureSignature { [weak self] (signature) in
       if let signature = signature {
        print("Capture Signature: \(signature.image)")
        print("Capture time: \(signature.date)")
