  func scrollViewDidScroll(_ scrollView: UIScrollView) {
        // viewKJNavigation is my declared KJNavigationViewAnimation property in ViewController class
        viewKJNavigation.scrollviewMethod?.scrollViewDidScroll(scrollView)
  }
  func scrollViewWillBeginDragging(_ scrollView: UIScrollView) {
        viewKJNavigation.scrollviewMethod?.scrollViewWillBeginDragging(scrollView)
  }
  func scrollViewDidEndDragging(_ scrollView: UIScrollView, willDecelerate decelerate: Bool) {
        viewKJNavigation.scrollviewMethod?.scrollViewDidEndDragging(scrollView, willDecelerate: decelerate)
  }
  func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
        viewKJNavigation.scrollviewMethod?.scrollViewDidEndDecelerating(scrollView)
