ios - 在 tableView Swift 中选择 textField 时打开 New ViewController

Question

我在 tableView 中使用一个 textField 并通过使用 indexPath.row 获取不同的数据但问题是我正在尝试打开一个新的ViewController在 tableView 中选择特定文本字段时.

UITableViewCell 类:

class AddCustomerCell: UITableViewCell {


@IBOutlet weak var textfield: SkyFloatingLabelTextField!

override func awakeFromNib() {
    super.awakeFromNib()
}

}

UITableView 数据源和委托(delegate)方法:-

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return 3
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    guard let cell = self.tableView.dequeueReusableCell(withIdentifier: "customerCell", for: indexPath) as? AddCustomerCell else {
        return UITableViewCell()
    }
    cell.textfield.delegate = self
    cell.textfield.placeholder = fieldArr[indexPath.row]["title"]
    cell.textfield.title = fieldArr[indexPath.row]["title"]
    cell.selectionStyle = .none

    if indexPath.row == 0 {

        cell.textfield.text = self.fullName
        cell.textfield.keyboardType = .default
    }
    else if indexPath.row == 1 {

        cell.textfield.text = self.email
        cell.textfield.keyboardType = .emailAddress
    }

    else if indexPath.row == 2 {
        cell.textfield.text = self.phoneNumber
        cell.textfield.keyboardType = .numberPad
    }
    else if indexPath.row == 3 {
        cell.textfield.text = self.areaSalesMen
        cell.textfield.keyboardType = .default
    }

    else {
        cell.textfield.isSecureTextEntry = false

    }

    return cell
}

UITableView didSelect 行方法

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let indexPath = tableView.indexPathForSelectedRow!
    print("index \(indexPath.row)")

    if indexPath.row == 0 {
        print("full name is selceted")
    }
    else if indexPath.row == 1 {

    }
    else if indexPath.row == 2 {

    }
    else if indexPath.row == 3 {
        let vc = AreaSalesMenListViewController.instantiate(fromAppStoryboard: .Main)
        self.navigationController?.pushViewController(vc, animated: true)
    }

这是 UItextField 扩展:-

extension AddCustomerViewController: UITextFieldDelegate {

func textFieldDidEndEditing(_ textField: UITextField) {
    if let indexPath = self.tableView.indexPath(forItem: textField) {
        if indexPath.row == 0 {
            //firstName
            self.fullName = textField.text ?? ""

        }
        else if indexPath.row == 1 {
            //lastName
            self.email = textField.text ?? ""

        }
        else if indexPath.row == 2 {
            //userId
            self.phoneNumber = textField.text ?? ""

        }
        else if indexPath.row == 3 {
            //asm
            self.areaSalesMen = textField.text ?? ""
            let vc = AreaSalesMenListViewController.instantiate(fromAppStoryboard: .Main)
            self.navigationController?.pushViewController(vc, animated: true)
        }

我要开新 ViewController当 textField在 indexPath.row == 3 中选择.我怎样才能做到这一点。请帮忙？

Answer 1

在 cellForRow方法添加以下行来设置 textField 的标签:

cell.textfield.tag = indexPath.row

在 textFieldDidBeginEditing添加以下代码以检测第 4 行中选定的 textField 表示 indexPath.row == 3 .

func textFieldDidBeginEditing(_ textField: UITextField) {

    if textField.tag == 3 {

        textField.resignFirstResponder()

        self.areaSalesMen = textField.text ?? ""
        let vc = AreaSalesMenListViewController.instantiate(fromAppStoryboard: .Main)
        self.navigationController?.pushViewController(vc, animated: true)
    }
}

我希望这能帮到您。
