我的一位测试者报告说，我的应用程序在她的手机上反复崩溃，当然，当我过去查看它时，没有任何问题。但我调出了崩溃日志，并试图弄清楚如何阅读这些东西。其中两个看起来很相似(一个在下面)。我只是需要有人在我盯着这些东西的时候握一下我的手。我最初怀疑是内存问题，但后来有人说内存泄漏不会导致崩溃，除非你自己进行溢出，而且这个日志没有提到任何关于内存的事情。谁能给我提示一下可能发生了什么事?

据我所知，iOS有一个看门狗，随时检查运行的应用程序。当应用程序超过20秒没有响应时，应用程序将自动终止。不确定这里是否发生了这种情况，但可能就是这种情况。
我会开始查看应用程序启动时运行的进程。有些人可能会遇到这种问题，当他们有很多应用程序加载并在后台运行时，处理速度变慢，这可能会显示为应用程序不响应。
