Question

我正在使用带有uitextfield的单个单元格来显示包含用户名，电子邮件ID，电话号码的表单。但是我想在按下下一个按钮的同时将光标移动到下一个字段。

我正在使用这样的代码：

  func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    let userNameCell = self.profileManagement!.cellForRow(at: IndexPath(row: 0, section: 0)) as? RegistrationFieldTableViewCell!
    let emailIDCell = self.profileManagement!.cellForRow(at: IndexPath(row: 1, section: 0)) as? RegistrationFieldTableViewCell!

    if textField == userNameCell {
      textField.resignFirstResponder()
      emailIDCell?.becomeFirstResponder()
      return false
    } else if textField == emailIDCell {
      textField.resignFirstResponder()
      return false
    }
    return true
  }

索引路径代码行的单元格如下：

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    // create a new cell if needed or reuse an old one
    let regCell = profileManagement.dequeueReusableCell(withIdentifier:"regFirstCell", for: indexPath)as? RegistrationFieldTableViewCell
    regCell?.registrationField.tag = indexPath.row
    regCell?.registrationFieldImage.image = fieldImages[indexPath.row]
    let nameFields = NSLocalizedString( regFieldsNames[indexPath.row], comment: "")
    regCell?.registrationField.placeholder = nameFields
    regCell?.registrationField.autocorrectionType = .no
    regCell?.registrationField.keyboardType = UIKeyboardType.default
    regCell?.showPassword.isHidden = true
    //Swith case for giving keypad to textfields
    switch indexPath.row {
    case 0:
      regCell?.registrationField.text = self.name
      regCell?.registrationField.isSecureTextEntry = false
    case 1:
      regCell?.registrationField.text = self.emailId
      regCell?.registrationField.textColor = UIColor.black
      regCell?.registrationField.isUserInteractionEnabled = true
    case 2:
      regCell?.registrationField.text = self.civilId
      regCell?.registrationField.textColor = UIColor.lightGray
      regCell?.registrationField.isUserInteractionEnabled = false
    case 3:
      regCell?.registrationField.text = "+965 \(self.phoneNumber)"
      regCell?.registrationField.isUserInteractionEnabled = false
    case 4:
      regCell?.registrationField.isSecureTextEntry = true
      regCell?.registrationField.text = "abhijith123"
      regCell?.showPassword.isHidden = true
      regCell?.registrationField.isUserInteractionEnabled = false
    default:
      print("Something else")
    }
    return regCell!
  }

但是当按下键盘上的下一个按钮时，它不会切换到下一个文本字段。为什么会这样？我的代码出了什么问题？

在按下swift3中的下一个按钮时，光标不会进入UITableView中的下一个文本字段
