ios - 如何快速在同一个 UIView 中创建自定义 UI Date PickerViews

Question

我试图在同一个 viewController 上有两个不同的日期选择器 View ，并让它们代表不同的数据。我尝试了不同的方法来做到这一点，但是两个日期选择器 View 都显示相同的数据，但不能把它们放在一起。我是快速编程的新手。任何帮助都会很棒!

 @IBOutlet weak var EventStart: UITextField!
var datepicker = UIDatePicker()
var datepicker2 = UIDatePicker()
@IBOutlet weak var EventEnd: UITextField!

override func viewDidLoad() {
    super.viewDidLoad()

    createDatePicker()
    Event.delegate = self
    eventName.delegate = self
    // Do any additional setup after loading the view.
}
func createDatePicker(){

    datepicker.datePickerMode = .dateAndTime
    datepicker2.datePickerMode = .dateAndTime
    let toolbar = UIToolbar()
    toolbar.sizeToFit()
    let doneButton = UIBarButtonItem(barButtonSystemItem: .done, target: nil, action: #selector(donePressed))
    toolbar.setItems([doneButton], animated: false)
    EventEnd.inputAccessoryView = toolbar
    EventEnd.inputView = datepicker2
    EventStart.inputAccessoryView = toolbar
    EventStart.inputView = datepicker
}

func donePressed(){
    let dateFormatter = DateFormatter()
    dateFormatter.dateStyle = .medium
    dateFormatter.timeStyle = .none
    EventStart.text = dateFormatter.string(from: datepicker.date)
    EventEnd.text = dateFormatter.string(from: datepicker2.date)
    print(EventStart)
    print(EventEnd)
    self.view.endEditing(true)
}

@IBOutlet weak var EventStart: UITextField!
var datepicker = UIDatePicker()
var datepicker2 = UIDatePicker()
@IBOutlet weak var EventEnd: UITextField!

override func viewDidLoad() {
    super.viewDidLoad()

   self.addDatePicker(datepicker, textfield:EventStart , selector: #selector(ViewController.donePressed))
    self.addDatePicker(datepicker2 , textfield:EventEnd ,selector: #selector(ViewController.donePressed2))

    // Do any additional setup after loading the view.
}


func addDatePicker(_ datepicker : UIDatePicker, textfield: UITextField, selector: Selector) {


    let toolbar = UIToolbar()
    toolbar.sizeToFit()
    let doneButton = UIBarButtonItem(barButtonSystemItem: .done, target: nil, action:selector)
    toolbar.setItems([doneButton], animated: false)


    textfield.inputAccessoryView = toolbar
    textfield.inputView = datepicker

}

func donePressed(){
    let dateFormatter = DateFormatter()
    dateFormatter.dateStyle = .medium
    dateFormatter.timeStyle = .none
    EventStart.text = dateFormatter.string(from: datepicker.date)
    print(EventStart)
    self.view.endEditing(true)
}

func donePressed2(){
    let dateFormatter = DateFormatter()
    dateFormatter.dateStyle = .medium
    dateFormatter.timeStyle = .none
    EventEnd.text = dateFormatter.string(from: datepicker2.date)
    print(EventEnd)
    self.view.endEditing(true)
}
