可以识别按钮点击，但无法删除或添加tableview单元内的任何子视图

问题描述

所以现在我在两个不同的文件中有两个类。一个是用作大型机的视图控制器，另一个是用于填充大型机的视图（其中有几个）。我是编程新手，因此遇到了巨大的视图控制器问题，因此这是我改变这一问题的方式。（请注意，代码在拆分为不同的文件之前按预期工作）

import UIKit
import SwiftUI
import MapKit
import DateScrollPicker
var collectionview: UICollectionView!
var collectionview2: UICollectionView!
var cellId = "Cell1"
var cellId2 = "Cell2"

class logbookController:  UIViewController,UITableViewDelegate,UITableViewDataSource,UISearchBarDelegate,UIGestureRecognizerDelegate,MKMapViewDelegate,UICollectionViewDataSource,UICollectionViewDelegateFlowLayout{

var topCard: topCardDeck!      //how I call the other views
var midCardBookVar: midCardBook!  //how I call the other views

override func viewDidLoad() {
    super.viewDidLoad()

    topCard = topCardDeck(frame: CGRect.zero)
    
    midCardBookVar = midCardBook(frame: CGRect.zero)

    background.backgroundColor = .white
                
    //add views
    self.view.addSubview(background)
    background.addSubview(topCard)
    background.addSubview(midCardBookVar)
    
    topCard.translatesAutoresizingMaskIntoConstraints = false
    midCardBookVar.translatesAutoresizingMaskIntoConstraints = false
    
    topCard.topAnchor.constraint(equalTo: self.view.topAnchor).isActive = true
    topCard.bottomAnchor.constraint(equalTo: self.view.bottomAnchor).isActive = true
    topCard.leftAnchor.constraint(equalTo: self.view.leftAnchor).isActive = true
    topCard.rightAnchor.constraint(equalTo: self.view.rightAnchor).isActive = true
    
    midCardBookVar.topAnchor.constraint(equalTo: self.view.topAnchor,constant: 1).isActive = true
    midCardBookVar.bottomAnchor.constraint(equalTo: self.view.bottomAnchor).isActive = true
    midCardBookVar.leftAnchor.constraint(equalTo: self.view.leftAnchor).isActive = true
    midCardBookVar.rightAnchor.constraint(equalTo: self.view.rightAnchor).isActive = true

func tableView(_ tableView: UITableView,heightForRowAt indexPath: IndexPath) -> CGFloat {
       var cellHeight:CGFloat = CGFloat()
       
       cellHeight = self.view.frame.height * 1/8
      
       return cellHeight
   }

func tableView(_ tableView: UITableView,heightForHeaderInSection section: Int) -> CGFloat {
          return 0
   }
   func tableView(_ tableView: UITableView,willdisplayHeaderView view: UIView,forSection section: Int) {
       guard let header = view as? UITableViewheaderfooterView else { return }

       header.clipsToBounds = true
   }

//我试图使这段代码起作用：topCard.removeFromSuperview（）和midCardBook.removeFromSuperview（）打印声明有效，所以我知道点击正在注册

func tableView(_ tableView: UITableView,didSelectRowAt indexPath: IndexPath) {
}
func tableView(_ tableView: UITableView,titleForHeaderInSection section: Int) -> String? {
        return sections[section] as? String
    }
func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int {
       return fruit.count
}

func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
       let cell = tableView.dequeueReusableCell(withIdentifier: "Cell",for: indexPath) as! JumpsTableViewCell
            cell.backgroundColor = .clear   
            cell.altitude.text = "Alt: 12,000 ft."
            cell.favoriteView.image = UIImage(named: "ProfileFavorite")
            cell.number.image = UIImage(named: "Numb 7")

            cell.numberLabel.text = "#"
            cell.dropzoneName.text = "\(fruit[indexPath.row])"
            cell.skydiveDate.text = DateFormatter.localizedString(from: NSDate() as Date,dateStyle: .short,timeStyle: .short)
        return cell
}

}

///这是我分割部分代码的地方。如您所见，委托和数据源已设置为主控制器logbook-controller。

class MidCardDeckBook: UIView {

let topCardDates = UIView()
var LogbookController = logbookController()
var myTableView: UITableView!

@IBAction func cloSEOverlay() {
   UIView.animate(withDuration: 0.5,animations: {
           self.alpha = 0.0
       }) { (_) in
           self.removeFromSuperview()
       }
   }


override init(frame: CGRect){
  super.init(frame: frame)
    
    topCardDates.backgroundColor = UIColor.black.withAlphaComponent(0.85)
    let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
    layout.sectionInset = UIEdgeInsets(top: 0,left: 0,bottom: 0,right: 0)
    layout.itemSize = CGSize(width: self.frame.width,height: 700)
    layout.scrollDirection = .horizontal
    collectionview = UICollectionView(frame: self.frame,collectionViewLayout: layout)
    collectionview.dataSource = LogbookController
    collectionview.delegate = LogbookController
    collectionview.register(FreelancerCell.self,forCellWithReuseIdentifier: cellId)
    collectionview.showsverticalScrollIndicator = false
    collectionview.backgroundColor = UIColor.clear
    
    let layout2: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
    layout2.sectionInset = UIEdgeInsets(top: 0,right: 0)
    layout2.itemSize = CGSize(width: self.frame.width,height: 700)
    layout2.scrollDirection = .vertical

    myTableView = UITableView()
    myTableView.register(JumpsTableViewCell.self,forCellReuseIdentifier: "Cell")
    myTableView.dataSource = LogbookController
    myTableView.delegate = LogbookController
    myTableView.backgroundColor = .clear
    myTableView.frame = CGRect(x: 0,y: 0,width: 200,height: 20)

    topCardDates.roundCorners([.topLeft,.topRight],radius: 5.0)

    self.addSubview(topCardDates)
    topCardDates.addSubview(collectionview)
    topCardDates.addSubview(collectionview2)
    topCardDates.addSubview(myTableView)

    topCardDates.translatesAutoresizingMaskIntoConstraints = false
    collectionview.translatesAutoresizingMaskIntoConstraints = false
    collectionview2.translatesAutoresizingMaskIntoConstraints = false
    myTableView.translatesAutoresizingMaskIntoConstraints = false

    topCardDates.bottomAnchor.constraint(equalTo: self.bottomAnchor).isActive = true
    topCardDates.widthAnchor.constraint(equalTo: self.widthAnchor).isActive = true
    topCardDates.heightAnchor.constraint(equalTo: self.heightAnchor,multiplier: 1).isActive = true
    
    collectionview.topAnchor.constraint(equalTo: topCardDates.topAnchor,constant: 10).isActive = true
    collectionview.leftAnchor.constraint(equalTo: topCardDates.leftAnchor,constant: 10).isActive = true
    collectionview.widthAnchor.constraint(equalTo: topCardDates.widthAnchor,multiplier: 2/3).isActive = true
    collectionview.heightAnchor.constraint(equalTo: topCardDates.heightAnchor,multiplier: 1/12).isActive = true

    myTableView.leftAnchor.constraint(equalTo: self.leftAnchor).isActive = true

    myTableView.bottomAnchor.constraint(equalTo: self.bottomAnchor).isActive = true

}

required init(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented ")
}
}

我有一个名为topCardClass的类似类，该类中嵌入了一堆uiview和按钮。同样，我可以从logbookcontroller中访问按钮操作选择器，因为print语句可以工作，但是一旦我尝试从控制器中添加或删除视图，它就无法工作。不过没有错误。
