swift - 如何使用 Storyboard将字符串传递到另一个 Controller (textViewController)Swift 3

Question

1. 创建模型

class model: NSObject {
    var title: String = ""
}

在方法 print 中

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell =  tableView.dequeueReusableCell(withIdentifier: "itemCell") as! itemTableViewCell
    let person = items[indexPath.row]
    cell.itemLabel.text = person.value(forKey: "name") as? String
    m.title = cell.itemLabel.text!
    print(m.title)

    return cell
}

字符串不起作用

class textViewController: UIViewController {

    @IBOutlet var textView: UITextView!

    override func viewDidLoad() {
        super.viewDidLoad()

       let V = ViewController()
        textView.text = V.m.title
    }

 }

您必须使用此方法将字符串传递给新的 View Controller :

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "AdYourIdentifierFromStoryboardHere"
    {
        if let destinationVC = segue.destinationViewController as? textViewController {
            destinationVC.title = title
        }
    }
}
