        super.viewDidLoad()
        
        // For TableView
        viewKJNavigation.setupFor(Tableview: yourTableView,
                                  viewController: self)
        // If you want your animation up to statusbar.
        viewKJNavigation.topbarMinimumSpace = .statusBar
        
        // If you want blurr background of navigation view.
        viewKJNavigation.isBlurrBackground = true
        
        // assign delegate of TableView, CollectionView OR ScrollView with self.
        tableview.delegate = self
}

// For CollectionView
viewKJNavigation.setupFor(CollectionView: yourCollectionView,
                          viewController: self)

// For ScrollView
viewKJNavigation.setupFor(Scrollview: yourScrollView,
                          viewController: self)

extension ViewController: UIScrollViewDelegate {
  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)
  }
}
