EKEventEditViewController 不会关闭

Question

我在 Helper-Class 中展示我的 EKEventEditViewController，如下所示：

func showAddAppointmentController(withDate date:Date) {
    let eventVC = EKEventEditViewController()
    eventVC.editViewDelegate = self
    eventVC.eventStore = eventStore

    eventVC.event?.title = "Test appointment"
    eventVC.event?.startDate = date
    eventVC.event?.endDate = date.addingTimeInterval(3600)

    UIApplication.shared.keyWindow?.rootViewController?.present(eventVC, animated: true, completion: nil)
}

一切正常，显示了控制器，但是当我按下 "Add" 或 "Cancel" 时，没有任何反应，只有以下控制台输出：

[EKCalendarItemLocationInlineEditItem isSubitemAtIndexSaveable:] - Location Inline Edit Item didn't have a text label on its non conference location cell; will return NO

我已经按如下方式实现了委托，但是没有调用该方法（不打印，断点也不起作用）

extension CalendarHelper : EKEventEditViewDelegate {
    func eventEditViewController(_ controller: EKEventEditViewController, didCompleteWith action: EKEventEditViewAction) {
        print("Delegate called!")
        controller.dismiss(animated: true) {
            self.delegate?.didFinish()
        }
    }
}

好的，错误出在别处，是我的错。我在代码中创建了 CalendarHelper，而不是将其作为 class 的属性保存，因此一旦显示日历，助手就被删除并且不再作为委托可用。

private var calendarHelper:CalendarHelper?

override func viewDidLoad() {
    super.viewDidLoad()
    calendarHelper = CalendarHelper(delegate: self)
}

func showCalendar() {
    calendarHelper.showCalendar()
}

而不是

func showCalendar() {
    CalendarHelper(delegate: self).showCalendar()
}
