CLKComplicationDataSource : 수백 번 호출 된 getTimelineEntries 대리자

Question

Watch app complication에서 TimeTravel을 지원하려고합니다. 이 코드를 고려하십시오.

내가 응용 프로그램을 죽일 때까지 왜 이러한 위임 메서드가 반복적으로 호출되는지 이해할 수 없습니다.

OS가 이러한 메소드를 호출해야하기 때문에 내가 뭘 잘못하고 있을지 궁금해. WatchOS 버그일까요?

func getTimelineEntries(for complication: CLKComplication, after date: Date, limit: Int, withHandler handler: @escaping ([ CLKComplicationTimelineEntry]?) -> Void) { 
    // Call the handler with the timeline entries after to the given date 

    let interval = stride(from:0.0, through:60, by: 10.0) 

    var entries: [CLKComplicationTimelineEntry]? = nil 

    switch complication.family { 

    case .circularSmall: 
     entries = interval.flatMap({ minutes in 
      entryForCircularSmall(date: date.addingTimeInterval(60.0 * minutes)) 
     }) 
     handler(entries) 

    case .utilitarianLarge: 
     entries = interval.flatMap({ minutes in 
      entryForUtilitarianLarge(date: date.addingTimeInterval(60.0 * minutes)) 
     }) 

     handler(entries) 

    default: 
     handler(nil) 
    } 

    print("future timelineEntries limit: \(limit), date: \(date), entries: \(entries?.count)") 
} 

func getTimelineEndDate(for complication: CLKComplication, withHandler handler: @escaping (Date?) -> Void) { 
    let date = Date().addingTimeInterval(60.0 * Double(240)) 
    print("timeline end: \(date)") 
    handler(date) 
}
