Question

我正在像这样在辅助类中展示我的EKEventEditViewController：

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，显示控制器，但是一旦我按下“添加”或“取消”，除了以下控制台输出，什么都没有发生：

[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，但是未调用该方法（不打印，并且断点也不起作用）

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

好吧，错误出在别的地方，我很糟糕。我是在代码中创建CalendarHelper的，而不是将其作为类的属性保存的，因此，一旦显示了日历，该帮助器即被删除，不能再作为委托使用。

private var calendarHelper:CalendarHelper?

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

func showCalendar() {
    calendarHelper.showCalendar()
}

代替

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

EKEventEditViewController不会关闭
