Table View Cell 没有初始化器

Question

我试图在单击按钮时将 table 视图单元格属性显示到不同的 table 视图单元格中。我正在使用故事板。我添加了水平和垂直堆栈以包含图像和标签属性。当用户单击显示按钮时，我想将此属性显示到另一个 table 视图单元格中。在 cellFor 行函数中，我定义了按钮操作属性。我收到以下错误。Class 'DetailsViewCell' 没有初始值设定项。 不能在属性初始值设定项中使用实例成员 'mc'；属性初始值设定项运行在 'self' 可用之前

这是两个视图控制器的屏幕截图。

这是代码。

 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
//        guard let cell = tableView.dequeueReusableCell(withIdentifier: MovieCell.identifier, for: indexPath) as? MovieCell
//        else { return UITableViewCell() }
        
        let cell = tableView.dequeueReusableCell(withIdentifier: MovieViewCell.identifier, for: indexPath) as! MovieViewCell
        
        
        cell.showButton.tag = indexPath.row
        cell.showButton.addTarget(self, action: Selector("movieDetails"), for: .touchUpInside)
        
        let row = indexPath.row
        let title = presenter.getTitle(by: row)
        let overview = presenter.getOverview(by: row)
        let data = presenter.getImageData(by: row)
        cell.configureCell(title: title, overview: overview, data: data)
        return cell
    }
}

这是标识符 class 中带有 table 视图单元格的代码。

class MovieViewCell: UITableViewCell {
    
    static let identifier = "MovieViewCell"
    
    @IBOutlet weak var mainStackView: UIStackView!
    
    @IBOutlet weak var movieImage: UIImageView!
    
    @IBOutlet weak var movieTtile: UILabel!
    
    @IBOutlet weak var movieOverview: UILabel!
    
    @IBOutlet weak var showButton: UIButton!
    
    @IBAction func movieDetails(_ sender: UIButton) {

        
        var  dc : DetailsViewCell
        movieTtile = dc.movieTitle
        movieOverview = dc.movieOverview
        movieImage = dc.movieImage
        
        
    }
    
    
    func configureCell(title: String?, overview: String?, data: Data?) {
        
        movieTtile.text = title
        movieOverview.text = overview
        
        if let imageData = data{
            movieImage.image = UIImage(data: imageData)
        }
    }
}

这是详细信息视图单元格的代码。

class DetailsViewCell: UITableViewCell {
    
    @IBOutlet weak var movieTitle: UILabel!
    
    @IBOutlet weak var movieOverview: UILabel!
    
    @IBOutlet weak var movieImage: UIImageView!
    

         var mc : MovieViewCell
        
         movieTitle = mc.movieTtile
         movieOverview = mc.movieOverview
         movieImage = mc.movieImage
        
    
    
}

Answer 1

import UIKit

var loginData = ["", "", ""]

class LoginDataCell: UITableViewCell, UITextFieldDelegate {

    @IBOutlet weak var txtLoginData: UILabel!

    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }

    func textFieldDidEndEditing(_ textField: UITextField) {
    if textField.tag == 0 {
       loginData[0] = textField.text
    } else if textField.tag == 1 {
      loginData[1] = textField.text
    } else if textField.tag == 2 {
      loginData[2] = textField.text
    }
    }

}
