        override func viewDidLoad() {
            super.viewDidLoad()
            tblView.estimatedRowHeight = 50
            tblView.rowHeight = UITableViewAutomaticDimension
            tblView.register(UINib(nibName: "SegmentedAttachmentCell", bundle: Bundle.main ), forCellReuseIdentifier: "Cell")
            iphoneCheck () // Iphone x Check
            initalSegmentSelected () // To Show First Index
        }

           func initalSegmentSelected () {
                self.segmentCtrl?.selectedSegmentIndex = 0
                screen = screenType.Media
                self.screenTypeData()
        }
   //MARK:- SegmentControllerUI
    func showTopSegmentControllerOnNavigationBar()
    {
        let appearance = SMSegmentAppearance()
        appearance.segmentOnSelectionColour = UIColor.DTColor()
        appearance.segmentOffSelectionColour = UIColor.clear
        appearance.titleOnSelectionFont = UIFont.systemFont(ofSize: 15.0)

        appearance.titleOnSelectionColour = UIColor.white

        segmentCtrl = SMSegmentView(frame: CGRect(x: 10.0, y: 4.0, width: UIScreen.main.bounds.size.width-20.0, height: 36.0), dividerColour: UIColor.DTColor(), dividerWidth: 3.0, segmentAppearance: appearance)
        segmentCtrl!.addTarget(self, action: #selector(ChatAttachmentsViewController.selectSegmentInSegmentView(_:)), for: .valueChanged)
        segmentCtrl!.addSegmentWithTitle(title: "Media", onSelectionImage: nil, offSelectionImage: nil,badgeCount: nil)

        segmentCtrl!.layer.borderColor = UIColor.DTColor().cgColor
        segmentCtrl!.layer.borderWidth = 2.0
        segmentCtrl!.layer.cornerRadius = 5
        segmentController.addSubview(segmentCtrl!)
        segmentController.backgroundColor = UIColor.LTColor()
    }
     // Setting Table
        func screenTypeData() {
            if screen == screenType.Media {
                tblView.isHidden = true
                self.tblView.isScrollEnabled = false
                attachmentsCollectionView.isHidden = false
                self.attachmentsCollectionView.isScrollEnabled = true
                self.attachmentsCollectionView.reloadData()
            }
            else if  screen == screenType.Document {
                tblView.dataSource = self
                tblView.delegate = self
                attachmentsCollectionView.isHidden = true
                self.attachmentsCollectionView.isScrollEnabled = false
                tblView.isHidden = false
                self.tblView.isScrollEnabled = true
                self.tblView.reloadData()
            }
        }

在screentypedata中设置tableview数据源和委托是否正确？或者我应该在viewdidload上设置它（问题是它在第一次点击时加载表也导致了很多时间，所以如何优化它）

我怀疑的问题：

每当我选中分段控件时，如果在screentypedata中设置它会一次又一次地复制数据源并委托吗？
如何优化解决方案，以便在我初始点击时集合视图重新加载（Datsource和委托工作）不是
tableview？

分段控制器设置表段中的代理和数据源？
