Question

我正在尝试使用Swift中的API创建Google Calendar事件。我现在有点失去了如何解决这个问题。更具体地说，创建一个GTLRCalendar_Event对象以通过GTLRCalendarQuery_EventsInsert.query()。有什么方法可以解决这个问题吗？

我写了以下代码

var newEvent: GTLRCalendar_Event = GTLRCalendar_Event()
        newEvent.summary = name

        //set GTLRDateTimes
        var startTime: GTLRDateTime = GTLRDateTime(date:startTimeObject!, offsetMinutes: offsetMinutes)
        var endTime: GTLRDateTime = GTLRDateTime(date:endTimeObject!, offsetMinutes: offsetMinutes)

        newEvent.reminders?.useDefault = 0

        newEvent.start?.dateTime = startTime
        newEvent.end?.dateTime = endTime

        let service: GTLRCalendarService = GTLRCalendarService()
        let query:GTLRCalendarQuery_EventsInsert = GTLRCalendarQuery_EventsInsert.query(withObject: newEvent, calendarId:"primary")
        service.executeQuery(query, completionHandler: {(_ callbackTicket: GTLRServiceTicket, _ event: GTLRCalendar_Event, _ callbackError: Error?) -> Void in
            print("executed query")
            if callbackError == nil {
                print("added")
                print(newEvent.summary);
            }
            else {
                print("add failed")
                print(callbackError)
            }
            } as? GTLRServiceCompletionHandler)

我在Swift 4中使用它。我基于谷歌的Java代码示例，因为它是最相似的。我希望这能回答你所有的问题。我相信有一个更漂亮的方法可以做到这一点，但我不知道。 :)

//Declares the new event
var newEvent: GTLRCalendar_Event = GTLRCalendar_Event()

//this is setting the parameters of the new event
newEvent.summary = ("Google I/O 2015")
newEvent.location = ("800 Howard St., San Francisco, CA 94103")

//I ran into some problems with the date formatting and this is what I ended with. 

//Start Date. The offset adds time to the current time so if you run the         program at 12:00 then it will record a time of 12:05 because of the 5 minute offset 

let startDateTime: GTLRDateTime = GTLRDateTime(date: Date(), offsetMinutes: 5)
let startEventDateTime: GTLRCalendar_EventDateTime = GTLRCalendar_EventDateTime()
startEventDateTime.dateTime = startDateTime
newEvent.start = startEventDateTime
print(newEvent.start!)

//Same as start date, but for the end date
let endDateTime: GTLRDateTime = GTLRDateTime(date: Date(), offsetMinutes: 50)
let endEventDateTime: GTLRCalendar_EventDateTime = GTLRCalendar_EventDateTime()
endEventDateTime.dateTime = endDateTime
newEvent.end = endEventDateTime
print(newEvent.end!)


let service: GTLRCalendarService = GTLRCalendarService()

//The query 
let query =
GTLRCalendarQuery_EventsInsert.query(withObject: newEvent, calendarId:"Past your calendar ID here this is specific to the calendar you want to edit and can be found under the google calendar settings")

//This is the part that I forgot. Specify your fields! I think this will change when you add other perimeters, but I need to review how this works more. 
query.fields = "id";

//This is actually running the query you just built
self.service.executeQuery(
       query,
       completionHandler: {(_ callbackTicket:GTLRServiceTicket, 
                            _  event:GTLRCalendar_Event,
                            _ callbackError: Error?) -> Void in} 
                           as? GTLRServiceCompletionHandler
           )
      }

在此主题上资源匮乏的时候，我遇到了同样的问题，这些步骤是

->使用Google日历帐户配置您的应用

1-转到https://console.developers.google.com/，添加一个具有应用程序包ID和名称的新项目

2-转到仪表板，单击“启用API和服务”，然后选择一个日历API服务并启用它。

3-从侧面菜单中选择凭据，然后点击页面顶部的CREATE CREDENTIALS链接并添加OAuth客户端ID

4-open Firebase控制台https://console.firebase.google.com/u/0/

5-单击添加项目，然后选择您现有的应用并继续

6-按照此处的https://firebase.google.com/docs/ios/setup步骤进行操作，直到下载“ GoogleService-Info.plist”并将其添加到您的应用中 ->编写代码以将事件添加到Google日历

1-按照这些步骤添加Google登录 https://developers.google.com/identity/sign-in/ios/sign-in?ver=swift

2- //为Google日历的用户创建一个事件

func addEventoToGoogleCalendar(summary : String, description :String, startTime : String, endTime : String) {
    let calendarEvent = GTLRCalendar_Event()

    calendarEvent.summary = "\(summary)"
    calendarEvent.descriptionProperty = "\(description)"

    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "dd/MM/yyyy HH:mm"
    let startDate = dateFormatter.date(from: startTime)
    let endDate = dateFormatter.date(from: endTime)

    guard let toBuildDateStart = startDate else {
        print("Error getting start date")
        return
    }
    guard let toBuildDateEnd = endDate else {
        print("Error getting end date")
        return
    }
    calendarEvent.start = buildDate(date: toBuildDateStart)
    calendarEvent.end = buildDate(date: toBuildDateEnd)

    let insertQuery = GTLRCalendarQuery_EventsInsert.query(withObject: calendarEvent, calendarId: "primary")

    service.executeQuery(insertQuery) { (ticket, object, error) in
        if error == nil {
            print("Event inserted")
        } else {
            print(error)
        }
    }
}

// Helper to build date
func buildDate(date: Date) -> GTLRCalendar_EventDateTime {
    let datetime = GTLRDateTime(date: date)
    let dateObject = GTLRCalendar_EventDateTime()
    dateObject.dateTime = datetime
    return dateObject
}
// Helper for showing an alert
func showAlert(title : String, message: String) {
    let alert = UIAlertController(
        title: title,
        message: message,
        preferredStyle: UIAlertController.Style.alert
    )
    let ok = UIAlertAction(
        title: "OK",
        style: UIAlertAction.Style.default,
        handler: nil
    )
    alert.addAction(ok)
    present(alert, animated: true, completion: nil)
}
