func getTimelineEndDate(for complication: CLKComplication, withHandler handler: @escaping (Date?) -> Void) {
    handler(Date(timeIntervalSinceNow: 60 * 30))
}

我也曾尝试从中的handle后台任务方法安排更新，ExtensionDelegate.swift但它似乎也不起作用。

func scheduleNextRefresh() {

    let userInfo = ["lastActiveDate" : Date(),
                    "reason" : "updateWeekNumber"] as Dictionary

    WKExtension.shared().scheduleBackgroundRefresh(withPreferredDate: fireDate, userInfo: userInfo as NSSecureCoding) { (error) …
