推出iOS SIGABRT

Question

我最近设置Crashlytics从我的iOS应用程序接收崩溃日志，我继续收到SIGABRT崩溃日志，但我找不到它来自哪里。

如果你可以帮我一点，这是崩溃日志：

感谢您的帮助！

编辑：为了清楚，我多次收到此崩溃日志，我无法重现我的测试设备上的错误

尝试在该十六进制代码上执行print对象，有时可以提供一些见解。

会留下这个评论，但由于某种原因无法对你的帖子发表评论。

似乎你正在删除/删除你的webThread（UIWebView？）中的applicationDelegate（applicationDidEnterBackground等）中的某些内容，如果你关闭/重新打开你的应用程序，那就不再存在了。
