Google Calendar API in swift return return = nil while return recurringEventId

Question

当返回循环时，它返回所有事件，但重复任务返回queryForEventsListWithCalendarId = nil和recurringEventId = id如何获取循环规则，以了解此事件是每天、每周还是每月重复

func fetchEvents(){

    let query = GTLQueryCalendar.queryForEventsListWithCalendarId("primary")
    query.maxResults = 30

    query.timeMin = NSDate()

    query.singleEvents = true
    query.orderBy = kGTLCalendarOrderByStartTime
    service.executeQuery(
        query,
        delegate: self,
        didFinishSelector: "displayResultWithTicket:finishedWithObject:error:"
    )
}

Answer 1

最后，在尝试了我找到的所有查询后，我找到了答案，以获得具有重复模式"Daily - Weekly - Monthly“的事件。我应该使用以下查询

let query = GTLQueryCalendar.queryForEventsListWithCalendarId("primary")
