ios - 使用取消和保存按钮操作将 Swift DatePicker 显示到 UIAlertController

Question

我的场景，我试图在 UIAlertController 中显示 TimePicker(仅显示 HH:MM 和 AM 或 PM)，并带有取消和保存按钮操作。我试过下面的代码，但它不工作。

let myDatePicker: UIDatePicker = UIDatePicker()
    myDatePicker.timeZone = NSTimeZone.local
    myDatePicker.frame = CGRect(x: 0, y: 15, width: 270, height: 200)
    let alertController = UIAlertController(title: "\n\n\n\n\n\n\n\n", message: nil, preferredStyle: UIAlertController.Style.alert)
    alertController.view.addSubview(myDatePicker)
    let selectAction = UIAlertAction(title: "Ok", style: UIAlertAction.Style.default, handler: { _ in
        print("Selected Date: \(myDatePicker.date)")
    })
    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertAction.Style.cancel, handler: nil)
    alertController.addAction(selectAction)
    alertController.addAction(cancelAction)
    present(alertController, animated: true, completion:{})

通过使用下面的行修复了这个问题

myDatePicker.datePickerMode = .time
