iOS 13 收到推送通知时崩溃?



我们在iOS 13上遇到了很多以下崩溃:

带有以下消息:

Fatal Exception: NSInternalInconsistencyException this request has been neutered - you can't call -sendResponse: twice nor after encoding it +[_CFXNotificationTokenRegistration keyCallbacks]

有谁知道是什么导致了这次崩溃?以下行15 UIKitCore 0x19d341558 -[UIHandleRemoteNotificationAction sendResponse:] + 128表示在收到远程通知时发生这种情况,我猜,但不确定。这是否与接收远程通知时未正确调用fetchCompletionHandler回调有关?感谢您的任何建议,谢谢:)

我认为即使它是一个可选方法,你也应该实现fetchCompletionHandler。 正如苹果在文档中提到的:

如果未及时调用完成处理程序,则应用将终止

快速修复:正确实现此委托...iOS 13应该让你走。

旁注:iOS 13 对所有历史背景的东西都非常挑剔,苹果添加了这种看门狗,如果你看起来没有在学术上使用背景功能,就会杀死你......对于许多带有VoIP推送的应用程序来说,同样悲伤的故事;-(

虽然我不知道 Crashlytics 的实现细节,但以前众所周知的使用Data对象注册远程通知的模式在 iOS 13 上不再受支持,并且可能会导致您的崩溃。

这个答案解释了差异:

iOS 13 是否有获取设备通知令牌的新方法?
