我的一位测试人员报告说我的应用程序在她的手机上反复崩溃，当然当我去看它时没有任何问题。但我拉了崩溃日志，并试图弄清楚如何阅读这些东西。其中两个看起来很相似（一个在下面发布）。在盯着这些时，我只需要有人握住我的手。我最初怀疑内存问题，但后来有人说内存泄漏不会导致崩溃，除非你自己泛滥，这个日志没有提到任何关于内存的事情。任何人都可以给我任何关于可能发生的事情的提示吗？

答案 0 :(得分：0)
根据我的理解，iOS有一个监视程序，可以检查始终运行的应用程序。当应用程序响应时间超过20秒时，应用程序将自动终止。不确定这是不是这里发生了什么，但可能是这种情况。
我开始研究在应用程序启动时运行的进程。有些人在后台加载并运行大量应用程序时会遇到这种问题，从而减慢处理速度，这可能会导致应用程序无法响应。
