                UIView.animate(withDuration: 0.5, animations: {
                    self.view.transform = CGAffineTransform.identity
                })
            }.didHide { (event) in
            }.willShow { (event) in
                let moveDistance = 100
                UIView.animate(withDuration: 0.5, animations: {
                    let transform = CGAffineTransform(translationX: 0, y: CGFloat(-(moveDistance)))
                    self.view.transform = transform
                })
            }.didShow { (eevnt) in
