删除 Google 日历活动

Question

如何从我的应用程序中删除特定的谷歌日历活动？ 这是我必须获取谷歌日历事件的代码。 如果我点击表格视图单元格菜单，当我点击删除时，我会在表格视图上显示所有事件，并显示删除选项，然后应删除所选事件。

    func fetchEvents() {
        let query = GTLRCalendarQuery_EventsList.query(withCalendarId: "primary")
        query.maxResults = 10
        query.timeMin = GTLRDateTime(date: Date())
        query.singleEvents = true
        query.orderBy = kGTLRCalendarOrderByStartTime
        service.executeQuery(
            query,
            delegate: self,
            didFinish: #selector(displayResultWithTicket(ticket:finishedWithObject:error:)))
    }

在 UITextView 中显示开始日期和事件摘要

    @objc func displayResultWithTicket(
        ticket: GTLRServiceTicket,
        finishedWithObject response : GTLRCalendar_Events,
        error : NSError?) {

        if let error = error {
            showAlert(title: "Error", message: error.localizedDescription)
            return
        }

        var outputText = ""
        if let events = response.items, !events.isEmpty {
            for event in events {
                let start = event.start!.dateTime ?? event.start!.date!
                let startString = DateFormatter.localizedString(
                    from: start.date,
                    dateStyle: .short,
                    timeStyle: .short)
                eventDateArray.add(start.date)


                let dataDic = ["fullTimeAndDate":startString , "tag":"red", "eventType":event.summary!] // MonthDataModel(fullTimeAndDate: seprated[1], tag: "red", appointmentType: event.eTag)
                eventArray.add(dataDic)

                outputText += "\(startString) - \(event.summary!)\n"
                print("Output ", startString , event )
            }
            UserDefaults.standard.set(eventDateArray, forKey: "EventDataArray")
            UserDefaults.standard.set(NSKeyedArchiver.archivedData(withRootObject: eventArray), forKey: "EventArray")


            UserDefaults.standard.synchronize()
        } else
        {
            outputText = "No upcoming events found."
        }
        print("Output Text",outputText)
        showAlert(title: "Event Sync Succesfully!", message:"")
    }

请指导我，我也是 swift 和堆栈溢出的新手。

我正在尝试使用此代码删除日历事件，但没有成功。

  func deleteGoogleCalendarEvent() {

        let query = GTLRCalendarQuery_EventsDelete.query(withCalendarId: "primary", eventId: self.del_Event_id)

        service.executeQuery(query, GTLRServiceCompletionHandler: nil)
    }

Answer 1

您将在需要提供calendarId 和eventId 的地方使用Events: delete 来执行此操作。对于 Swift 中的代码实现，请遵循以下指南：

Swift Google Calendar: Delete an Event

func chilkatTest() {
    let rest = CkoRest()
    var success: Bool

    //   Provide a previously obtained OAuth2 access token.
    let oauth2 = CkoOAuth2()
    oauth2.AccessToken = "OAUTH2_ACCESS_TOKEN"
    rest.SetAuthOAuth2(oauth2)

    success = rest.Connect("www.googleapis.com", port: 443, tls: true, autoReconnect: true)
    if success != true {
        print("\(rest.LastErrorText)")
        return
    }

    let sbResponse = CkoStringBuilder()
    success = rest.FullRequestNoBodySb("DELETE", uriPath: "/calendar/v3/calendars/support@chilkatcloud.com/events/1p7fb5vob7vm57fepk4p1teft9", sb: sbResponse)
    if success != true {
        print("\(rest.LastErrorText)")
        return
    }

    if rest.ResponseStatusCode.integerValue != 204 {
        print("Received error response code: \(rest.ResponseStatusCode.integerValue)")
        print("Response body:")
        print("\(sbResponse.GetAsString())")
        return
    }

    print("Example Completed.")

}

Answer 2

哇！！我得到了它。只需要对删除函数调用做一些修改，对删除函数的选择器函数做一些工作

   func deleteGoogleCalendarEvent() {

        let query = GTLRCalendarQuery_EventsDelete.query(withCalendarId: "primary", eventId: self.del_Event_id)

        service.executeQuery(query, delegate: self, didFinish: #selector(deleteResultWithTicket(ticket:finishedDelete:error:)))
    }

这里是选择器（deleteResultWithTicket）

@objc func deleteResultWithTicket(
        ticket: GTLRServiceTicket,
        finishedDelete response: GTLRCalendarQuery_AclDelete,
        error : NSError?) {

        if error != nil {
            print(error?.localizedDescription!)
            return
        }
        self.fetchGoogleCalendarEvents()
    }

如果你想对谷歌日历事件进行写操作，请确保范围，你必须设置范围 = [kGTLRAuthScopeCalendar]。
