隐藏最后一页上的页面视图控制器点

Question

我想在最后一页隐藏页面视图控制器指示点！我的问题是我可以在最后一页隐藏它们，但当我回到上一页时我可以再次看到它们

这是我的代码

func pageViewController(_ pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) {
    self.pageVC.currentPage = pageViewController.viewControllers!.first!.view.tag

 if(viewControllers!.first?.view.tag == 4 ) {

    if (VCArr.last!.isViewLoaded)

    {
        print("Last Page")
        self.pageVC.pageIndicatorTintColor = UIColor.clear
        self.pageVC.currentPageIndicatorTintColor = UIColor.clear
        self.pageVC.backgroundColor = UIColor.clear
    }



        if (VCArr.last!.isViewLoaded) {

    if(viewControllers!.first?.view.tag != 4 ) {

        self.pageVC.pageIndicatorTintColor = UIColor.lightText
        self.pageVC.currentPageIndicatorTintColor = UIColor.white
        self.pageVC.backgroundColor = UIColor.white

    }
