ios - 分析此崩溃报告

Question

我收到了这份崩溃报告，并“符号化”了它。即使在那之后，我仍然无法理解我的崩溃是从哪里来的。

应用程序启动后立即崩溃。

这是我的崩溃报告:

此报告是否意味着崩溃发生在“hashWithSecretKeyUpdateUser”函​​数调用中？

有办法了解更多有关崩溃的信息吗？

此时我无法让我的应用程序崩溃

Answer 1

它看起来像“段错误”(SIGSEGV)，这意味着您的代码访问的内存不存在或无效。根据您的崩溃报告，看起来 hashWithSecretKeyUpdateUser 从“strlen + 12”访问错误或无效的内存，我相信您传递给 hashWithSecretKeyUpdateUser 的字符串不存在或错误。
