extension UIScrollView {
    override public func  touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
        self.nextResponder()?.touchesBegan(touches, withEvent: event)
    }
    public override func touchesMoved(touches: Set<NSObject>, withEvent event: UIEvent) {
        self.nextResponder()?.touchesMoved(touches, withEvent: event)
    }
    public override func touchesEnded(touches: Set<NSObject>, withEvent event: UIEvent) {
        self.nextResponder()?.touchesEnded(touches, withEvent: event)

    }
