CLKComplicationDataSource: делегат getTimelineEntries вызывается сотни раз

Question

CLKComplicationDataSource: делегат getTimelineEntries вызывается сотни раз

Я пытаюсь поддержать TimeTravel в приложении Complication. Рассмотрим этот код.

Я не могу понять, почему эти методы делегата вызываются неоднократно, пока я не убью приложение.

Интересно, что я могу делать не так, поскольку ОС вызывает эти методы. Это какая-то ошибка WatchOS?

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)
}

Небольшая выдержка из журнала консоли:

Как выясняется, делегат вызывался слишком много раз, потому что я продолжал бы предоставлять записи графика времени для той же самой даты.

В моем коде была ошибка (не показана здесь), связанная с созданием объектов CLKComplicationTimelineEntry. Вместо использования даты, предоставленной делегатом, я использовал вызов Date() (очевидно, скопированный из реализации getCurrentTimelineEntry метод).

Я нахожу впечатляющим, однако, что WatchOS вызывал делегата тысячи раз.

Я нахожу для этого другую причину. Записи, которые вы возвращаете для обработчика, должны охватывать не менее 25 часов, иначе getTimelineEntriesбудет продолжать вызывать до тех пор, пока не получит достаточно записей.

      func getTimelineEntries(for complication: CLKComplication, after date: Date, limit: Int, withHandler handler: @escaping ([CLKComplicationTimelineEntry]?) -> Void) {
    var entries: [CLKComplicationTimelineEntry] = // .... some code
    handler(entries)
}
