【问题描述】：
使用 Skylink SDK 为 VoIP 应用程序添加 VoIP 推送（通过 Pushwoosh）后，我遇到了崩溃，仅在我的一台设备（iPhone 5s 8.4）上。看起来是关于视频捕捉的。另一位测试人员感觉很好（iPhone 5s、iPhone 6、8.4.1、9.1），当我在没有 VoIP 推送的情况下将其强制连接到房间时，我的 iPhone 4s 没有崩溃。
UPD : 在其他设备上随机重现崩溃
这是崩溃日志：

有什么想法吗？

【问题讨论】：
-
我对这个症状的第一个怀疑是有问题的设备有不同的设备设置。在不同的语言环境中，或在设备设置中以相反方式设置 12/24 开关可能会产生奇怪的症状。
-
@HotLicks UPD 2：崩溃在其他设备上随机重现
-
实际的堆栈跟踪是什么样的？
-
@Aft3rmath 不是。当应用程序崩溃时，它会编写一个崩溃报告，其中包括每个线程的堆栈状态——以及其他信息——正如它在您的第一个控制台日志摘录中所说的那样。 ("Nov 13 19:43:18 iPhone-5s-Aft3rmath ReportCrash[1306] : 为进程 SkylinkP2P[1282] 制定崩溃报告")
-
下一步：查找有关如何使用“symbolicatecrash”将所有这些数字转换为与您的代码相关的信息的参考资料。
