通过 UIButton 添加自定义单元格

Question

我正在尝试添加一个全新的自定义单元格，该单元格具有从库中选取图像和从文本字段中输入标题的功能，我在情节提要中有两个视图控制器（1.带有图片和两个标签的提要视图控制器，所有这些都在TableView.2. 第二个 ViewController 负责通过从库中选取图像并通过 textField 创建两个标签来添加新图像，其中两个我连接到一个类中（我不确定这是否合法）。所以我的问题是，在选择图像并输入标签并单击按钮后，对象不会附加到 UI 中，但在数组的打印语句中也会附加。

    import UIKit
    import Firebase

 class ChatViewController: UIViewController, UITableViewDelegate,    UITableViewDataSource{
    
    override func viewDidLoad() {
        super.viewDidLoad()
        //        cardTableView.isHidden = true
    }
    
    @IBOutlet weak var titleTextField: UITextField!
    @IBOutlet weak var descriptionTextField: UITextField!
    @IBOutlet weak var imageView: UIImageView!
    
    @IBAction func AddPurchase(_ sender: UIButton) {
        titles.append(titleTextField.text!)
        pictures.append(imageView.image!)
        descriptions.append(descriptionTextField.text!)
        print(titles)
        print(descriptions)
        print(pictures)
        
    }


    @IBOutlet var cardTableView: UITableView!
    
    var pictures: [UIImage] = [UIImage(named: "banan.jpg")!, UIImage(named: "pineapple.jpg")!, UIImage(named: "dragonfruit.jpg")!]
    var titles: [String] = ["Banana Paradise", "Pineapple island", "The Dragon's Fruit"]
    var descriptions: [String] = ["Hello", "Hello", "Hello"]
    
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return pictures.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cardCell", for: indexPath) as! CardCell
        
        cell.configure(picture: pictures[indexPath.row], title: titles[indexPath.row], description: descriptions[indexPath.row])
        
        return cell
    }
    
    //Add
    
    
    @IBAction func didTapButton(_ sender: UIButton) {
        let vc = UIImagePickerController()
        vc.sourceType = .photoLibrary
        vc.delegate = self
        vc.allowsEditing = true
        present(vc, animated: true)
    }
 
    
 }


    extension ChatViewController:  UIImagePickerControllerDelegate, UINavigationControllerDelegate{
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        
        
        if let imageShow = info[UIImagePickerController.InfoKey(rawValue: "UIImagePickerControllerEditedImage")] as? UIImage{
            imageView.image = imageShow
        }
        
        picker.dismiss(animated: true, completion: nil)
    }
    
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        picker.dismiss(animated: true, completion: nil)
    }
 }

()]()]()

我尝试将图像和文本附加到按钮函数中的数组。请帮我解决这个问题。
