我正在使用PushKit/CallKit开发我的Swift应用程序，它是纯Swift、在Xcode 13.1上测试，使用iOS 15和iOS 14.7（两个物理设备）+PHP后端。在测试过程中，我发现每次语音推送接收事件时，无论它是在后台还是未启动，我的应用都会崩溃。只有当它在前台时，一切正常，所有情况都被处理，推送也是OK的，呼叫也能被报告，应用程序按预期工作。我认为这是由于[PKPushRegistry _terminateAppIfThereAreUnhandledVoIPPushes]+192引起的。你可以在下面看到完整的崩溃日志。在沙盒（从Xcode构建的开发版本）和生产（adhoc分发版本）苹果APN网址上均出现相同的问题。我的问题是：为什么我的应用程序在前台运行正常（所有推送都能正确地报告到CallKit），而在后台却无法报告某些事情？难道在我的AppDelegate中的一个方法func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion:@escaping () -> Void)中不应该是相同的逻辑吗？是否存在必须特别处理VoIP推送的应用程序启动或进入前台的情况？我已经为此挣扎了5天，这里任何帮助都将不胜感激！一些背景：它是基于WKWebView的应用程序，其中PushKit部分旨在通过从服务器发送的推送发起视频呼叫（通话本身在网页上完全运行，使用Agora引擎）。重点在于让应用程序知道以下内容：
- 电话即将开始（例如，有人坐在网页上并给我打电话）
- 电话正在更改其状态（例如，接听电话）
- 电话未被接听或拒绝
- 电话结束（例如，我正在与某人交谈，他挂断了电话并离开了对话）
我如何处理它（简要逻辑说明）：接收推送，检查其有效载荷，根据需要启动新呼叫（报告到CallKit）或更新呼叫（我已经向CallKit报告一个呼叫）。然后，根据负载JSON中的操作字段，我正在执行各种操作，例如（如上所述）开始新呼叫、接受呼叫（例如，移动到Web视图中的某个特定页面）、将我的状态返回到服务器、结束正在进行的呼叫等。无论如何（这很重要！），我将ANY推送报告给CallKit作为新呼叫，在其他地方回答、拒绝、结束等。
我没有任何情况不向CallKit报告信息，但唯一可能的情况是当我收到的推送在负载中没有“action”字段时（例如，推送来自未知结构、格式错误或已损坏）。现在，话虽如此，我也考虑使用CallKit处理这种情况，无论是拒绝还是类似的操作。

更新：当在Xcode中运行时，我可以看到后台应用程序正在接收推送并尝试管理它，将状态发送回服务器。

在我的函数pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: @escaping () -> Void)完成之前，发生了一些事情。
当我尝试在其中设置断点以跟踪逻辑时，我立即收到来自调试器的信号9终止。
这可能是由于线程问题导致的吗？我使用异步方式将反馈发送到服务器，所以可能需要太长时间，而在我报告我的调用之前，didReceiveIncomingPushWith payload的执行就已经完成了吗？
