Swift UITextField inputView with UITableView - ios

Question

I'm trying to set a tableView to fill a UITextField via .inputView method. And actually, it's not working at all.. I don't know what I've missed...
Here is the test code I wrote, it works fine with UIPickerView but does not show anything with UITableView.. thanks for your support !
class ViewController: UIViewController, UITextFieldDelegate, UIPickerViewDelegate, UIPickerViewDataSource, UITableViewDelegate, UITableViewDataSource {
var itemPicker = UIPickerView()
var playerTableView = UITableView()
#IBOutlet weak var textFieldOne: UITextField!
#IBOutlet weak var textFieldTwo: UITextField!
var firstTextField = ["a", "b", "c", "d"]
var secondTextField = ["A", "B", "C", "D"]
override func viewDidLoad() {
super.viewDidLoad()
textFieldOne.delegate = self
textFieldTwo.delegate = self
itemPicker.delegate = self
itemPicker.dataSource = self
playerTableView.register(UITableViewCell.self, forCellReuseIdentifier: "playerCell")
playerTableView.delegate = self
playerTableView.dataSource = self
textFieldOne.inputView = itemPicker
textFieldTwo.inputView = playerTableView
}
// PickerView
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return firstTextField.count
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return firstTextField[row]
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
textFieldOne.text = firstTextField[row]
}
// TableView
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return firstTextField.count
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 100
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = playerTableView.dequeueReusableCell(withIdentifier: "playerCell")
if cell == nil {
cell = UITableViewCell(style: .default, reuseIdentifier: "playerCell")
}
cell?.textLabel?.text = firstTextField[indexPath.row]
return cell!
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
textFieldTwo.text = firstTextField[indexPath.row]
}
}
