swift – 如何从UITableViewCell获取文本字段的值？

此代码不检索任何值.

@IBAction func printBtnAction(_ sender: Any) {

    let cell = self.myTableView.dequeueReusableCell(withIdentifier: "manualAddC1") as! AddFriendC1Cell

    let alias = cell.aliasTextField.text!
    let primaryPhone = cell.primaryPhoneTextField.text!
    let secondaryPhone = cell.seondaryPhoneTextField.text!
    let email = cell.emailAddressTextField.text!

    print("Alias: \(alias), Phone: \(primaryPhone), Phone2: \(secondaryPhone), Email: \(email)")
}

这是TableView的屏幕截图

@IBAction func saveBtnAction(_ sender: Any) {

    let index = IndexPath(row: 0, section: 0)
    let cell: AddFriendC1Cell = self.myTableView.cellForRow(at: index) as! AddFriendC1Cell
    self.alias = cell.aliasTextField.text!
    self.primaryPhone = cell.primaryPhoneTextField.text!
    self.secondaryPhone = cell.seondaryPhoneTextField.text!
    self.email = cell.emailAddressTextField.text!

    print("Alias: \(self.alias), Phone: \(self.primaryPhone), Phone2: \(self.secondaryPhone), Email: \(self.email)")
}
