swift - 在 swift 中以编程方式在 tableviewcell 上执行 Root View Controller segue

Question

下面的代码创建一个 tableviewcell 并在其中放置一个对象。不存在将数据放入 tableviewcell 中的代码。我想要做的就是当用户单击 tableviewcell 时，它将传输到基本 View Controller 类。无需展示如何返回。

   var itemName : [NSManagedObject] = []
var theField = UITableView()

override func viewDidLoad() {
    super.viewDidLoad()


    theField.register(UITableViewCell.self, forCellReuseIdentifier: "MyCell")
}
 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let title = itemName[indexPath.row]
    let cell = theField.dequeueReusableCell(withIdentifier: "MyCell", for : indexPath)

    cell.selectionStyle = .default
    let attr1 = title.value(forKey: "name") as? String



    let text = [attr1].flatMap { $0 }.reduce("", +)
    cell.textLabel?.text = "\(text)"

    cell.textLabel?.textAlignment = .center

    cell.layoutMargins = UIEdgeInsets.zero




    cell.preservesSuperviewLayoutMargins = false
    cell.separatorInset = UIEdgeInsets.zero
    cell.layoutMargins = UIEdgeInsets.zero


    return cell

}

 @objc func moveRight() {

     //pass tableview cell
     let vce = fullScreen()
    vce.text = UITableViewCell




           vce.modalPresentationStyle = .overCurrentContext // actually .fullScreen would be better
           vce.present(vce, animated: true)}

Answer 1

假设你有一个数组titles

cell.textLabel?.text = titles[indexPath.row]

然后在此方法中执行操作:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    tableView.deselectRow(at: indexPath, animated: true)

    moveRight(titles[indexPath.row])

}

func moveRight(_ title:String) {
    //pass tableview cell
    let vc = fullScreen()
    vc.text = title
    self.navigationController!.pushViewController(vc, animated: true)        
}
