ios - 从 TextFields 获取 tableViewCell 的所有值

Question

我想使用 TextFields 从 TableViewCell 获取所有值，但我不明白如何通过单击按钮来做到这一点。

如果单击添加按钮，我可以添加新行。所以我可以制作任意数量的行。

我的代码在这里:

struct Section {
    let title: String
    var rows: [String]
}

class SettingsScheduleAndPricesViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate {

    var hall: Halls?

    var sections = [Section]()

    override func viewDidLoad() {
        super.viewDidLoad()
        sections = [Section(title: "Day of week", rows: []),
                    Section(title: "Second section", rows: [""]),
                    Section(title: "Third section", rows: [""])]
    }

    // MARK: - TableView
    func numberOfSections(in tableView: UITableView) -> Int {
        return sections.count
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return sections[section].rows.count
    }
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        if indexPath.section == 0 {
            ...
        } else if indexPath.section == 1 {
            let hourlyRateCell = tableView.dequeueReusableCell(withIdentifier: "hourlyRateCell", for: indexPath) as! SettingsHourlyRateCell
            return hourlyRateCell
        } else {
            ...
        }
    }

    func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
        return sections[section].title
    }

    func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        let frame: CGRect = tableView.frame
        if section == 0 {
            let headerView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: frame.size.width, height: frame.size.height))
            headerView.backgroundColor = #colorLiteral(red: 0.8039215803, green: 0.8039215803, blue: 0.8039215803, alpha: 1)
            return headerView
        } else if section == 1 {
            let addButton: UIButton = UIButton(frame: CGRect(x: frame.size.width - 50, y: 0, width: 50, height: 30))
            addButton.backgroundColor = UIColor.clear
            addButton.setTitleColor(#colorLiteral(red: 0.2588235438, green: 0.7568627596, blue: 0.9686274529, alpha: 1), for: .normal)
            addButton.setTitle(NSLocalizableAdd, for: .normal)
            addButton.addTarget(self, action: #selector(SettingsScheduleAndPricesViewController.addHourlyRate(sender:)), for: .touchUpInside)
            let headerView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: frame.size.width, height: frame.size.height))
            headerView.backgroundColor = #colorLiteral(red: 0.8039215803, green: 0.8039215803, blue: 0.8039215803, alpha: 1)
            headerView.addSubview(addButton)
            return headerView
        } else {
            ...
        }
    }

    @IBAction func saveBarButtonPressed(_ sender: Any) {

        // here I want to get all values from my Cell from my TextFields

    }

    @objc func addHourlyRate(sender: UIButton) {
        let newRow = ""
        append(row: newRow, in: 1)
    }

    func append(row : String, in section: Int) {
        let insertionIndex = sections[section].rows.count
        sections[section].rows.append(row)
        let indexPath = IndexPath(row: insertionIndex, section: section)
        tableView.insertRows(at: [indexPath], with: .automatic)
    }
}

class SettingsHourlyRateCell: UITableViewCell, UITextFieldDelegate {
    @IBOutlet weak var rubHourTF: UITextField!
}

我的模拟器示例:

在我的示例中，我需要从三行获取first、second和third字符串文本。并附加到空数组中或仅在控制台中打印。

在方法@IBAction func saveBarButtonPressed(_ sender: Any)中。

我找不到任何可以帮助我的东西。

也许我的方法会对某人有所帮助，但我仍然设法这样做。我只需在我的按钮中添加以下代码:

@IBAction func saveBarButtonPressed(_ sender: Any) {
    let countRowsOne = tableView.numberOfRows(inSection: 1)
        for index in 0...countRowsOne {
            let indexPath = IndexPath(row: index, section: 1)
            if let cell = tableView.cellForRow(at: indexPath) as? SettingsHourlyRateCell {
                ...
            }
            ...
        }
    }
}
