UItableview中的多页面视图控制器，当我选择或滑动页面时，我没有得到单元格索引路径吗？

Question

• 在UITableview中，有多个页面视图控制器和诸如数组之类的不同内容。
• 第一次显示良好，因为第一次我总是为所有单元格（数组）传递index = 0。
• 但是例如在tableview中向下滚动和向下滚动之后，在当前地址部分中：3页，在这里我想基于单元格索引路径数组传递受尊敬的数组，但是我无法获取单元格（页面）索引路径。

• 如果我基于此知道单元格索引路径，我会将受尊重的数据传递给contentpageviewcontroller。

  override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
  
      var cell: UITableViewCell!
      cell = tableView.dequeueReusableCell(withIdentifier: "pageviewCell", for: indexPath)
  
      self.pageViewController = (storyboard?.instantiateViewController(withIdentifier: "PageViewController"))! as! UIPageViewController
      self.pageViewController.delegate = self
      self.pageViewController.dataSource = self
      self.pageViewController.title = "\(indexPath.row-1)"
      pageViewController.setViewControllers([getViewControllerAtIndex(index: 0, indexPath: indexPath.row-1)], direction: UIPageViewControllerNavigationDirection.forward, animated: false, completion: nil)
      pageViewController.view.frame = CGRect(x: 5, y: 5, width: cell.contentView.frame.size.width-10, height: cell.contentView.frame.size.height-10)
  
      self.addChildViewController(pageViewController)
      cell.contentView.addSubview(pageViewController.view)
      self.pageViewController.didMove(toParentViewController: self)
  
      cell.backgroundColor = UIColor.gray
  
      return cell
  }
  
  func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController?
  {
      let pageContent: ProfilePageContentVC = viewController as! ProfilePageContentVC
  
      var index = pageContent.pageIndex
      if ((index == 0) || (index == NSNotFound))
      {
          return nil
      }
      index -= 1;
      return getViewControllerAtIndex(index: index, indexPath: Int(pageViewController.title!)!)
  }
  
  func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController?
  {
      let pageContent: ProfilePageContentVC = viewController as! ProfilePageContentVC
  
      var index = pageContent.pageIndex
      if (index == NSNotFound)
      {
          return nil;
      }
      index += 1;
      let val: NSString = pageListCountChkDict.value(forKey: self.pageViewController.title!) as! NSString
      //if (index == arrPageTitle.count)
      if (index == val.integerValue)
      {
          return nil;
      }
      return getViewControllerAtIndex(index: index, indexPath: Int(pageViewController.title!)!)
  }
  
  func getViewControllerAtIndex(index: NSInteger, indexPath: NSInteger) -> ProfilePageContentVC {
  
      let pageContentViewController = (storyboard?.instantiateViewController(withIdentifier: "ProfilePageContentVC"))! as! ProfilePageContentVC
  
      pageContentViewController.pageIndex = index
  
      let pageContentDict = NSMutableDictionary()
      let pageContentFinalArray = NSMutableArray()
  
      if objModel.finalDict.allKeys[indexPath] as! String == "EMPOFFHR" {
          pageContentFinalArray.add(pageContentDict)
          pageContentViewController.pageContentFinalArray = pageContentFinalArray as NSArray
          let pageTitleArray = ["HR Details"]
          pageContentViewController.pageTitleArray = pageTitleArray as NSArray
      }
  
      func presentationCount(for pageViewController: UIPageViewController) -> Int {
  
          let val: NSString = pageListCountChkDict.value(forKey: self.pageViewController.title!) as! NSString
          print("presentationCount :\(self.pageViewController.title!)")
          print("presentationCount :\(val)")
          return val.integerValue
      }
  
  
      func presentationIndex(for pageViewController: UIPageViewController) -> Int {
          return 0
      }
