Watchアプリケーションの複雑化でTimeTravelをサポートしようとしています。 このコードを検討してください。CLKComplicationDataSource：何百回も呼び出されたgetTimelineEntriesデリゲート
私は、アプリケーションを終了するまで、これらのデリゲートメソッドが繰り返し呼び出される理由を理解できません。
私は、OSがこれらのメソッドを呼び出す責任があるので、私が間違っていると思いますか。これはWatchOSのバグですか？
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)
}
