添加事件到日历-swift

获取日历事件权限

导入 importEventKit

let eventStore = EKEventStore.init()

weak var weakSelf = self

eventStore.requestAccess(to: EKEntityType.event, completion: {(isAllow, error) in

    if isAllow == true{

}else{             

    }

})

新增日历事件

let event = EKEvent.init(eventStore: eventStore)

event.title = “mm提醒” + “【拜访” + visitor + “】”

if visitStyle != nil{

event.notes = visitStyle

}

 event.calendar = eventStore.defaultCalendarForNewEvents

event.calendar.cgColor = colorLiteral(red: 0.4941176471, green: 0.8078431373, blue: 0.4392156863, alpha: 1).cgColor

event.calendar.title = “mm”

event.startDate = Date()

event.endDate =Date()+ 3600

print(event.calendar.calendarIdentifier)

event.addAlarm(EKAlarm(relativeOffset: -60))

do {

    try eventStore.save(event, span: .thisEvent, commit: true)

 DispatchQueue.main.async {

        //新增成功后的处理

 }

} catch {

     print(error)

}

查询和删除日历事件

let dfmatter = DateFormatter()

dfmatter.dateFormat=“yyyy-MM-dd HH:mm”

let startDate = dfmatter.date(from: self.model.return_visit_time!)!

weakSelf?.eventDate = startDate

let endDate = dfmatter.date(from: self.model.return_visit_time!)! + 3600

let predicate = self.eventStore.predicateForEvents(withStart: startDate, end: endDate, calendars: nil)

eventStore.enumerateEvents(matching: predicate, using: { (event, pointer) in

do {

        let _ = try self.eventStore.remove(event, span: .thisEvent)

       } catch {

           print(error)

 }

})

如果要删除指定日历事件

根据事件唯一标识符：event.calendar.calendarIdentifier，我们需要将生成事件的标识符保存，删除时予以对照即可。此外，日历事件无法编辑修改，如若要完成此效果，我们需删除旧事件、新增新事件来替换
