iOS - UIView或UIViewController应该处理状态到UI映射吗？

Question

我已经阅读了一些帖子，但我找不到这个问题的明确答案：在MVC框架中，谁应该负责UI的设置？我在两个选项之间取得平衡：

class ViewController: UITableViewController {
  private var users: [User]
  ...
  override func tableView(
    _ tableView: UITableView,
    cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    guard let cell = dequeueDataCell(id: "myCell") as? CellView else { return UITableViewCell() }

    cell.title.text = user?.name
    cell.subtitle.text = user?.nickname
    cell.action.isHidden = isSelected
    // other numerous UI set up on the cell

    return cell
  }
}

class CellView: UITableViewCell {
  @IBOutlet weak var title: UILabel?
  @IBOutlet weak var subtitle: UILabel?
  @IBOutlet weak var action: UIButton!
}

和

class ViewController: UITableViewController {
  private var users: [User]
  ...
  override func tableView(
    _ tableView: UITableView,
    cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    guard let cell = dequeueDataCell(id: "myCell") as? CellView else { return UITableViewCell() }

    cell.user = self.users[indexPath.row]
    cell.isSelected = false
    cell.refresh()

    return cell
  }
}

class CellView: UITableViewCell {
  @IBOutlet private weak var title: UILabel?
  @IBOutlet private weak var subtitle: UILabel?
  @IBOutlet private weak var action: UIButton!

  weak var user: User?
  var isSelected = false

  func refresh() {
    title.text = user?.name
    subtitle.text = user?.nickname
    action.isHidden = isSelected
    // other numerous UI set up on the cell
  }
}

到目前为止，我一直在使用大多数iOS教程中的第一种方法。但是我发现这使得UIViewController更长，而它们已经变得漫长而模糊，并且因为它混合了UI和状态逻辑而更难阅读。
