在不引用 App functions/classes 的情况下解释崩溃日志
Interpreting a crash log without references to App functions/classes
我在上一个应用程序中遇到 "random" 崩溃（大约 2% 的用户似乎遇到过崩溃）但我无法从崩溃日志中找到任何有用的信息。似乎我没有对我的代码的任何参考，我发现非常难以理解发生了什么以及这个崩溃是如何产生的......我在这里粘贴崩溃日志的相关部分，关于它的任何提示或想法？有什么明显的我想念的吗...

看来您的应用正在创建一个没有根视图控制器的 window。也许您的视图控制器无法创建。

您的问题似乎与 weird crash when launching app from Notification Center
相似
Either your code or a third-party library you are using is manually spinning the runloop. This is causing -workspaceDidEndTransaction: to be called re-entrantly and triggers a use after free. If you set a breakpoint on -[NSRunLoop runMode:beforeDate:] and -[NSRunLoop runUntilDate:], it should hit with the guilty code being on the previous stack frame.
While manually spinning the run loop is never recommended, if you can
delay doing it until your application finishes starting up (all the
launch app delegate calls received) you should avoid hitting this
crash.
