ios - 将数据从另一个 UITableView 传递到 UITableViewCell 中的文本字段(不使用 Segue)

Question

我有 2 个 Controller AddContactController 和 HomepageController。我想选择主页中的每一行(从 Web 服务加载 JSON 数据)。然后传递每一行的数据并导航到 AddContactController，它也是 TableViewCell。我该怎么做 ？我的代码有点乱。有什么建议吗？

AddContactController 类

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let myCell = tableView.dequeueReusableCell(withIdentifier: "cellId") as! AddContactCell
    let note = tableView.dequeueReusableCell(withIdentifier: "note") as! Note
    myCell.input_field.delegate = self
    note.input_field.delegate = self as? UITextViewDelegate

    if indexPath.section == 0 {
        myCell.nameLabel.text = items[indexPath.row]
        if (myCell.nameLabel.text == "Occupation")
        {
            myCell.input_field.attributedPlaceholder = NSAttributedString(string: "Occupation",
                                                                   attributes: [NSForegroundColorAttributeName:UIColor(red:0.81, green:0.81, blue:0.83, alpha:1.0)]) 
        }
        else if (myCell.nameLabel.text == "First Name"){
            myCell.input_field.attributedPlaceholder = NSAttributedString(string: "First Name",
                                                                          attributes: [NSForegroundColorAttributeName:UIColor(red:0.81, green:0.81, blue:0.83, alpha:1.0)])

        }
        else {
            myCell.input_field.attributedPlaceholder = NSAttributedString(string: "Last Name",
                                                                          attributes: [NSForegroundColorAttributeName:UIColor(red:0.81, green:0.81, blue:0.83, alpha:1.0)]) 
        }
        myCell.myContactController = self
        return myCell
    }
    else if indexPath.section == 1 {
        myCell.nameLabel.text = "Place"
        myCell.input_field.attributedPlaceholder = NSAttributedString(string: "Place",
                                                                      attributes: [NSForegroundColorAttributeName:UIColor(red:0.81, green:0.81, blue:0.83, alpha:1.0)])

        return myCell
    }
    else {
        return note
    }
}

主页 Controller 类

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let myCell = tableView.dequeueReusableCell(withIdentifier: "cellId", for: indexPath as IndexPath) as! RecordCell

    myCell.playButton.tag = indexPath.row
    myCell.playButton.addTarget(self, action: #selector(playAudio(sender:)), for: .touchUpInside)
    myCell.nameLabel.text = nameArray[indexPath.row]
    let fullNameArray = nameArray[indexPath.row].components(separatedBy: " ")
    let fname = fullNameArray[0].characters.first
    let lname = fullNameArray[1].characters.first
    var initials: String = ""
    if (fname != nil && lname != nil ) {
        initials.append(fname!)
        initials.append(lname!)
    }
    myCell.shortname.text = initials
    myCell.myTableViewController = self
    return myCell
}

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let storyboard = UIStoryboard(name: "InstanceStoryBoard", bundle: nil)
    let viewController = storyboard.instantiateViewController(withIdentifier: "viewControllerIdentifer") as! AddContactController
    viewController.
    self.navigationController?.pushViewController(viewController, animated: true)    
}

假定传递数据所需的所有内容都存储在此

var nameArray = [String]()

使用 indexPath 获取 selected row 的单元格 tableView.cellForRow(at: indexPath)

示例代码:

HomeViewCintroller

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let cell = tableView.cellForRow(at: indexPath) as! RecordCell
    let storyboard = UIStoryboard(name: "InstanceStoryBoard", bundle: nil)
    let viewController = storyboard.instantiateViewController(withIdentifier: "viewControllerIdentifer") as! AddContactController
    viewController.obj = cell.nameLabel.text
    self.navigationController?.pushViewController(viewController, animated: true)    
}

AddContactViewController

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{    
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell")
    cell.mytxt.text = obj
    return cell
}
