当我在启用画外音的情况下重新刷新页面时发生崩溃。 iOS内部发生的崩溃。我对这次事故不熟悉。 我被困在这场车祸中。有人能帮我吗？为什么会发生这次坠机？我怎样才能解决这个问题？请参阅下面的崩溃日志

在关闭画外音的情况下，你会遇到同样的崩溃吗？你能在这里添加一些代码吗？不，当画外音关闭时，崩溃没有发生。你能包括完整的日志，包括崩溃原因吗？这是一个不一致的问题，每50次崩溃一次，崩溃日志没有显示任何与我的代码相关的内容。这里不允许我添加完整的崩溃报告作为评论。无论如何，我会在这里添加操作系统版本和一些详细信息作为注释父进程：launchd[1]日期/时间：2015-06-29T07:04:42Z操作系统版本：iPhone OS 8.3（12F69）报告版本：104异常类型：SIGSEGV异常代码：0xc崩溃线程的SEGV_ACCERR:0，这是崩溃日志的上半部分。
