如何解决出现并发症的顺序是什么 我如何更改数据？
我之前问过一个关于如何刷新并发症并在那里得到一些帮助的问题，但我仍然不知道一切发生的顺序以及如何更新并发症数据。即使在 WKRefreshBackgroundTask
How do I refresh WatchApp complications
我的 WKRefreshBackgroundTask 看起来像这样并且在调用 scheduleBackgroundRefreshTasks():
func handle(_ backgroundTasks: Set<WKRefreshBackgroundTask>) {
print("__________________________________________________")
print("Handling a background task...")
print("App State: \(WKExtension.shared().applicationState.rawValue)")
print(GlobalVaribles.sharedInstance.currentTime)
print("__________________________________________________")
for task in backgroundTasks {
print("backgroundTasks = \(backgroundTasks)")
switch task {
// Handle background refresh tasks.
case let backgroundTask as WKApplicationRefreshBackgroundTask:
scheduleBackgroundRefreshTasks()
backgroundTask.setTaskCompletedWithSnapshot(true)
case let snapshottask as WKSnapshotRefreshBackgroundTask:
snapshottask.setTaskCompleted(restoredDefaultState: true,estimatedSnapshotExpiration: Date.distantFuture,userInfo: nil)
case let connectivityTask as WKWatchConnectivityRefreshBackgroundTask:
connectivityTask.setTaskCompletedWithSnapshot(false)
case let urlSessionTask as WKURLSessionRefreshBackgroundTask:
urlSessionTask.setTaskCompletedWithSnapshot(false)
case let relevantShortcutTask as WKRelevantShortcutRefreshBackgroundTask:
relevantShortcutTask.setTaskCompletedWithSnapshot(false)
case let intentDidRunTask as WKIntentDidRunRefreshBackgroundTask:
intentDidRunTask.setTaskCompletedWithSnapshot(false)
default:
task.setTaskCompletedWithSnapshot(false)
}
}
}
}
我可以看到 scheduleBackgroundRefreshTasks 打印 "Task scheduled with targetDate = \(targetDate).") 但没有数据发生变化。
