우리는 어떻게 내가 화면에가있는 모든 캘린더 이벤트를 동기화 할 수 있습니다, 내가 미리 알림 응용 프로그램을 개발하고 내 응용 프로그램

Question

에서 특정 캘린더를 추가/제거하려면? 그래서 내가 추가 된 캘린더 이벤트 만 동기화 할 수 있습니다.

Answer 1

당신이 빠른 사용하고 있다고 가정 할 때, 특정 달력

   eventStore.requestAccessToEntityType(EKEntityTypeEvent, completion: { 
        (granted, error) in 

     if (granted) && (error == nil) { 
         println("granted \(granted)") 

      println("error \(error)") 


      var event:EKEvent = EKEvent(eventStore: eventStore) 


      event.title = "Test Title" 

      event.startDate = NSDate() 

      event.endDate = NSDate() 

      event.notes = "This is a note" 

      event.calendar = newCalendar 

      eventStore.saveEvent(event, span: EKSpanThisEvent, error: nil) 

      println("Saved Event") 
     } 
     }) 

에 이벤트를 추가이

 // Create an Event Store instance 
      let eventStore = EKEventStore(); 

     // Use Event Store to create a new calendar instance 
     // Configure its title 
      let newCalendar = EKCalendar(forEntityType: .Event, eventStore: eventStore) 

     // Probably want to prevent someone from saving a calendar 
     // if they don't type in a name... 
        newCalendar.title = "Some Calendar Name" 

     // Access list of available sources from the Event Store 
        let sourcesInEventStore = eventStore.sources 

     // Filter the available sources and select the "Local" source to assign to the new calendar's 
     // source property 
        newCalendar.source = sourcesInEventStore.filter{ 
         (source: EKSource) -> Bool in 
      source.sourceType.rawValue == EKSourceType.Local.rawValue 
     }.first! 

     // Save the calendar using the Event Store instance 
        do 
        { 
         try eventStore.saveCalendar(newCalendar, commit: true) 

      NSUserDefaults.standardUserDefaults().setObject(newCalendar.calendarIdentifier, forKey: "EventTrackerPrimaryCalendar") 
        } 
         catch 
         { 
          let alert = UIAlertController(title: "Calendar could not save", message: (error as NSError).localizedDescription, preferredStyle: .Alert) 

      let OKAction = UIAlertAction(title: "OK", style: .Default, handler: nil) 

      alert.addAction(OKAction) 


      self.presentViewController(alert, animated: true, completion: nil) 
         } 
       } 
      } 

같은 달력을 만들 수 있습니다 그리고 특정 캘린더의 이벤트를 얻을 수

 func loadEvents() { 
      // Create a date formatter instance to use for converting a string to a date 
      let dateFormatter = NSDateFormatter() 

    dateFormatter.dateFormat = "yyyy-MM-dd" 

    // Create start and end date NSDate instances to build a predicate for which events to select 
      let startDate = dateFormatter.dateFromString("2016-01-01") 

    let endDate = dateFormatter.dateFromString("2016-12-31") 


    if let startDate = startDate, endDate = endDate { 
       let eventStore = EKEventStore() 

     // Use an event store instance to create and properly configure an NSPredicate 
       let eventsPredicate = eventStore.predicateForEventsWithStartDate(startDate, endDate: endDate, calendars: [newCalendar]) 

     // Use the configured NSPredicate to find and return events in the store that match 
       self.events = eventStore.eventsMatchingPredicate(eventsPredicate).sort(){ 
        (e1: EKEvent, e2: EKEvent) -> Bool in 
      return e1.startDate.compare(e2.startDate) == NSComparisonResult.OrderedAscending 

     } 
      } 
     }
