swift - 如何让 ClockKit 生成超过 100 个时间线条目？

Question

我正在尝试创建一个 ClockKit 复杂功能，为一个人的下一个轮类开始时间提供数据，但没有足够的时间线条目生成或生成得不够频繁，因此有时，数据在一定时间后不准确。

我已尝试调试并得出结论，仅创建了 100 个时间轴条目，适合每个方向 1:40 小时的日期，这对我的应用程序来说不够。我已经阅读了文档和延长时间线的方法，但发现它每天只能使用一定次数。

我在我的 getTimelineEntries(complication:date:limit:handler) 中加入了 print(String(limit) + "After") 以查看它生成了多少。

我该怎么做才能使我的并发症的时间线从 00:00 延长到 23:59？另外，为什么时间线不会在超过最 future 的条目时自动延长？这似乎与 Apple 对并发症的意图有悖常理。

我在下面包含了我的 ComplicationController.swift。

安排一个 backgroundRefresh 例如 future 一小时做一个extendTimeline .

要安排后台刷新，请在您的 ExtensionDelegate 中的 applicationDidFinishLaunching 中运行它，不要忘记在每次刷新时重新安排它。

让 minutesToRefresh = 60
WKExtension.shared().scheduleBackgroundRefresh(withPreferredDate: Date().addingTimeInterval(minutesToRefresh * 60), userInfo: nil, scheduledCompletion: scheduledCompletion)
