Question

是否有可以从Swift中的日历中删除所有事件的命令？

Answer 1

考虑到您使用 startDate ， endDate ， description 保存活动， title

var event:EKEvent = EKEvent(eventStore: eventStore)
                event.title = "Test Title"
                event.startDate = NSDate()
                event.endDate = NSDate()
                event.notes = "This is a note"
                event.calendar = eventStore.defaultCalendarForNewEvents
                eventStore.saveEvent(event, span: EKSpanThisEvent, error: nil)

然后您需要做的就是删除事件：

  var startDate=NSDate().dateByAddingTimeInterval(-60*60*24)
        var endDate=NSDate().dateByAddingTimeInterval(60*60*24*3)
        var predicate2 = eventStore.predicateForEventsWithStartDate(startDate, endDate: endDate, calendars: nil)

        println("startDate:\(startDate) endDate:\(endDate)")
        var eV = eventStore.eventsMatchingPredicate(predicate2) as [EKEvent]!

        if eV != nil {
            for i in eV {
                println("Title  \(i.title)" )
                println("stareDate: \(i.startDate)" )
                println("endDate: \(i.endDate)" )
              do{
                (try eventStore.removeEvent(i, span: EKSpan.ThisEvent, commit: true))
                }
                catch let error {
                }

            }
        }
    }

Answer 2

兼容Swift 3 ：

func removeAllEventsMatchingPredicate() {
    let startDate = NSDate().addingTimeInterval(60*60*24*(-2))
    let endDate = NSDate().addingTimeInterval(60*60*24*7)

    let predicate2 = eventStore.predicateForEvents(withStart: startDate as Date, end: endDate as Date, calendars: nil)

    print("startDate:\(startDate) endDate:\(endDate)")
    let eV = eventStore.events(matching: predicate2) as [EKEvent]!

    if eV != nil {
        for i in eV! {

            do{
                (try eventStore.remove(i, span: EKSpan.thisEvent, commit: true))
            }
            catch let error {
                print("Error removing events: ", error)
            }

        }
    }
}
