ios - 1 个 UIView 中带有 2 个选择器的 2 个文本字段

Question

我在 1UIView 中制作了一个带有 2 个选择器的 2 个文本字段，但我无法在正确的文本字段中显示正确的选择器，因为我不知道如何识别当前事件 View 。我尝试了一些带有标签的东西(但仅适用于选择器，不适用于文本字段)，并创建 var current = UITextField()

var genre = ["-","Homme","Femme"]
var Sport = ["-","Tennis"]
var picker = UIPickerView()
var currentTextField = UITextField()

override func viewDidLoad() {
        super.viewDidLoad()

 picker.delegate = self
    picker.dataSource = self
    GenderTextField.inputView = picker
    WitchSportTextField.inputView = picker

func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 1
    }
    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        if currentTextField == GenderTextField{
        return genre.count
        }else{
            return Sport.count
        }
    }

    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        if currentTextField == GenderTextField {
            GenderTextField.text = genre[row]
        }else{
            WitchSportTextField.text = Sport[row]
        }
    }
    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        if currentTextField == GenderTextField{
        return genre[row]
         }else{
            return Sport[row]
        }
    }

有人作为一个想法？

Answer 1

这是完整的代码

var genre = ["-","Homme","Femme"]
var Sport = ["-","Tennis"]
var genrepicker = UIPickerView()
var Sportpicker = UIPickerView()
var genretTextField = UITextField()
var SportTextField = UITextField()

override func viewDidLoad() {
        super.viewDidLoad()

    genrepicker.delegate = self
    genrepicker.dataSource = self

    Sportpicker.delegate = self
    Sportpicker.dataSource = self
    genretTextField.inputView = genrepicker
    SportTextField.inputView = Sportpicker

func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 1
    }
    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        if pickerView == genrepicker{
        return genre.count
        }else{
            return Sport.count
        }
    }

    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        if pickerView == genrepicker {
            GenderTextField.text = genre[row]
        }else{
            WitchSportTextField.text = Sport[row]
        }
    }
   func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        if pickerView == genrepicker{
        return genre[row]
         }else{
            return Sport[row]
        }
    }
