Ios 我如何诊断和解决WCSession sendMessage（uuyHandler:errorHandler:）上的崩溃？

我正在构建一个watchOS应用程序，它需要定期从配套的iPhone应用程序请求信息，以刷新复杂度

为了实现这一点，我有一个定期运行的

WKApplicationRefreshBackgroundTask

。它使用

WatchConnectivity

中的

sendMessage（uu2;：replyHandler:errorHandler:）

从iPhone应用程序请求信息，处理回复，并更新复杂度

这在大多数情况下对许多用户来说都是可靠的，但是，我看到Apple Watch在与

sendMessage（\uu∶replyHandler:errorHandler:）

相关的Xcode中崩溃，我担心这会导致用户错过复杂的更新。一些用户一直抱怨没有更新复杂度，因此我试图确定是否存在超出常规限制的问题，即复杂度在watchOS中刷新的频率

有人对我如何解决此问题有什么建议吗？或者，您对我如何更好地排除导致崩溃的故障并找出预防方法有什么建议吗

我在底部包含了一个完整的崩溃示例，以及处理后台任务的代码和处理从配对iPhone发送和接收值的代码

我从来不会在没有回复手柄的情况下发送信息，所以在iPhone上，我不认为这是问题所在。为了安全起见，我在iPhone上实现了delegate方法，它是一个空方法，不做任何事情

更新2020年1月30日：一位朋友建议，问题可能是任务仍在进行时，10秒计时器将任务标记为已完成，当挂起的任务完成时，会导致内存问题，但不确定该如何处理。也许这就是问题的核心

这是我在

extensionelegate

中的后台刷新代码：

func handle(_ backgroundTasks: Set<WKRefreshBackgroundTask>) {
    for task in backgroundTasks {
        switch task {
        case let backgroundTask as WKApplicationRefreshBackgroundTask:

            // set a timer in case it doesn't complete
            // the maximum allowed is 15 seconds, and then it crashes, so schedule the new task and mark complete after 10
            var timeoutTimer: Timer? = Timer.scheduledTimer(withTimeInterval: 10, repeats: false) { (timer) in

                self.scheduleBackgroundRefresh()

                backgroundTask.setTaskCompletedWithSnapshot(false)
            }

            // schedule the next refresh now in case the request crashes
            scheduleBackgroundRefresh()

            WatchConnectivityManager.shared.requestDataFromPhone()

            ComplicationManager.shared.reloadComplication()

            // as long as the expiration timer is valid, cancel the timer and set the task complete
            // otherwise, we'll assume the timer has fired and the task has been marked complete already
            // if it's marked complete again, that's a crash
            if let timerValid = timeoutTimer?.isValid, timerValid == true {
                timeoutTimer?.invalidate()
                timeoutTimer = nil
                backgroundTask.setTaskCompletedWithSnapshot(true)
            }

        default:
            // make sure to complete unhandled task types
            task.setTaskCompletedWithSnapshot(false)
        }
    }
}

private func scheduleBackgroundRefresh() {

    let fiveMinutesFromNow: Date = Date(timeIntervalSinceNow: 5 * 60)

    WKExtension.shared().scheduleBackgroundRefresh(withPreferredDate: fiveMinutesFromNow,
    userInfo: nil) { (error) in
        if let error = error {
            fatalError("\(error)")
        }
    }
}

我想你的朋友是对的：
当您将后台任务设置为完成时，系统将暂停您的应用程序，请参阅。
系统可以在没有警告的情况下清除挂起的应用程序，请参阅。
因此，如果发生这种情况，

replyHandler

或

errorHandler

将无法调用，应用程序将崩溃。
因此，您不能依靠

sendMessage

唤醒iOS应用程序并及时呼叫

replyHandler

。
我建议您在iOS上初始化并发症数据的传输。要定期这样做，您可以使用它唤醒您的iOS应用程序，并使用

transferCurrentCompliationUserInfo（：）

查看发送新的并发症数据。即使您的watch应用程序未运行，也会收到此

userInfo

，并且可以根据需要更新并发症数据

编辑：

虽然我上面的解决方案可能有效，但可能有一个更简单的解决方案：

可能不需要更新您的

ViewModel

来响应

sendMessage

，只需要更新复杂度即可。如果是这样，您只需将

sendMessage

与

replyHandler

和

errorHandler

设置为

nil

sendMessage

保证在将来唤醒iOS应用程序，即使watchOS应用程序已经处于非活动状态。iOS应用程序随后可以发送并发症数据，这些数据将立即显示。
此外，iOS应用程序可以将更新您的

ViewModel

的

userInfo

作为应用程序上下文发送。当watchOS应用程序再次激活时，它将可用，您可以更新

ViewModel

---

如果这适合您的用例，您可以在

sendMessage

之后立即删除计时器并完成后台任务

你能重现这次坠机吗？不，我不确定我怎样才能重现它。我经常在Apple Watch上使用该应用程序，但在Xcode中检查设备日志时没有任何崩溃。根据Xcode中的崩溃日志，它发生在所有不同类型的硬件上，新的和旧的。我很害怕。所以我想在僵尸打开的情况下跑步不会告诉你什么？在线程消毒剂打开的情况下运行不会告诉你任何事情？我必须对值班人员进行更多测试，然后再给你回复。谢谢你的建议。嗯，他们可能帮不上忙（与内存相关的崩溃通常是诊断性的（即，崩溃比实际问题晚得多）即使你可以复制，也很难找到。谢谢你的回复。不幸的是，此应用程序设计为脱机工作，没有服务器端组件，因此我不能使用服务器触发的静默推送通知。你知道有什么方法可以阻止调用

replyHandler

（并使手表应用程序崩溃）当后台任务由于计时器而已经完成时？大多数情况下，使用

replyHandler

的

sendMessage

是watchOS应用程序唤醒和从iOS应用程序请求数据的可靠方法，因此我希望找到一种方法来管理此异常。感谢您提出的更简单的解决方案建议！我认为使用combinat将

TransferCurrentCompliationUserInfo

和

transferUserInfo

响应

sendMessage

发送到iPhone可以提供我所需要的可靠性，即使在没有安装Compliations的情况下。我会尝试一下！
