如何使用 EventKit 删除某些/特定事件

Question

我需要删除标题为 certain/specific 的事件，我希望我可以 delete/remove 基于 eventID/Identifier 的事件。但我不知道如何在代码中做到这一点。我不知道如何为事件提供标识符并根据他们的 identifier/title.

将其删除

这是我用来保存事件的代码：

let eventStore = EKEventStore()
        let newEvent = EKEvent(eventStore: eventStore)

        newEvent.calendar = eventStore.defaultCalendarForNewEvents
        newEvent.title = self.eventNameTextField.text ?? "Some Event Name"
        newEvent.startDate = timeDatePicker.date
        newEvent.endDate = endTimeDatePicker.date
        newEvent.notes = "Ini adalah catatan"
        newEvent.location = "Jalan Sunda kelapa no.60"

        let eventAlarm = EKAlarm(relativeOffset: -60 * 10) // 10 minutes before the start date
        newEvent.alarms = [eventAlarm]


        do {
            try eventStore.save(newEvent, span: .thisEvent)
            print("Event has been saved")
        } catch {
            let alert = UIAlertController(title: "Event could not be saved", message: (error as NSError).localizedDescription, preferredStyle: .alert)
            let OKAction = UIAlertAction(title: "OK", style: .default, handler: nil)
            alert.addAction(OKAction)

            self.present(alert, animated: true, completion: nil)
        }

我知道我可以使用 evenStore.remove() ，但该方法需要 EKEvent 实例。我不明白如果使用该方法如何删除特定事件，如果我可以根据标识符删除事件会更容易

实际上 EKEvent 实例有一个名为 eventIdentifier 的只读属性。您无法修改此标识符，但您可以在保存事件后获取它。所以：

do { try eventStore.save(newEvent, span: .thisEvent) let id = newEvent.eventIdentifier ?? "NO ID" //Save your ID in your database or anywhere else so you can retrieve the event later print("Event has been saved with id \(id)") } catch { let alert = UIAlertController(title: "Event could not be saved", message: (error as NSError).localizedDescription, preferredStyle: .alert) let OKAction = UIAlertAction(title: "OK", style: .default, handler: nil) alert.addAction(OKAction) self.present(alert, animated: true, completion: nil) }

然后您可以使用其标识符获取事件

let event = eventStore.event(withIdentifier: id)

然后把这个EKEvent传递给eventStore.remove()
