How To Edit Tableview Cell Data with Core Data In Another View Controller

Question

I have a tableview that has data stored in core data and when the tableviewCell is tapped it opens another viewController with a label with the data on it. I want to have a textfield and a button on that viewController that when the button is tapped it updates the tableviewCell data and saves in core data .

Here is some code when I pass the data over Main View Controller :

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{
    var name2 = String()

    tableView.deselectRow(at: indexPath, animated: true)

    let name = itemName[indexPath.row]
    name2 = (name.value(forKey: "title") as? String)!

    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let secondVC = storyboard.instantiateViewController(withIdentifier: "secondView") as! SecondViewController
    secondVC.name = name2
    self.present(secondVC, animated: true, completion: nil)
}

Here is in the other view controller

var name = ""

override func viewDidLoad() {
    super.viewDidLoad()
    nameLabel.text = name

}

Now all I need is to be able to edit one of those tableviewCells from the second view controller and send it into the tableview in the first and update core data .

我建议您将第二个视图控制器中的数据保存到核心数据中，并在第一个视图控制器中将其获取并显示在表中。
