ios - 显示自定义标签和图像重复的 UITableViewCell

Question

图像仍然显示顶部和底部的单元格

我正在使用 indexPath.row 来确定要显示的图像和标签的类型，但不幸的是它也显示在表格的顶部和底部，因此复制下面的单元格是我的代码:

导入基金会 导入 UIKit

//custom cell

类 menuTableCells:UITableViewCell{

var menuName: String?
var menuIcon: UIImage?

var lblMenuName: UILabel = {
    let view = UILabel()
    view.translatesAutoresizingMaskIntoConstraints = false
    return view
}()

var menuImage: UIImageView = {
    let view = UIImageView()
    view.translatesAutoresizingMaskIntoConstraints = false
    return view
}()

override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
    super.init(style: style, reuseIdentifier: reuseIdentifier)

    self.addSubview(lblMenuName)
    self.addSubview(menuImage)

    //constraints for icons
    menuImage.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 20).isActive = true
    menuImage.topAnchor.constraint(equalTo: self.topAnchor, constant: 20).isActive = true
    menuImage.heightAnchor.constraint(equalToConstant: 35).isActive = true

    lblMenuName.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: -10).isActive = true

}

override func layoutSubviews() {
    super.layoutSubviews()

    if let menuName = menuName{
        lblMenuName.text = menuName
    }

    if let menuIcon = menuIcon {
        menuImage.image = menuIcon
    }
}

不要在运行时添加 UIImage 和 UILable 尝试使用自定义单元格。有关如何使用自定义和默认单元格的更多详细信息，请遵循本教程 Here

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "LabelCell", for: indexPath)

        let headline = headlines[indexPath.row]
        cell.textLabel?.text = headline.title
        cell.imageView?.image = UIImage(named: headline.image)

        return cell
    }
