Xamarin.iOS 的设备崩溃日志

Question

我在不同地点有一位客户使用“Ad-Hoc”部署测试我们的软件。他的应用程序崩溃了，我无法重现它。他给了我来自 XCode 管理器的崩溃日志，但我无法弄清楚如何将它们与我的 c#/Xamarin 解决方案相关联。

这是崩溃的线程（UI 线程）的日志。

对于应用程序MedXChangeiOS，我如何找出类/方法/行？

Answer 1

您需要 dSYM 目录用于您的客户的构建。

生成发布版本时，Xamarin.iOS 将自动在 YourApp.app 目录旁边创建一个 YourApp.app.dSYM 目录。当您向客户发送构建时，您必须将此目录保存在您机器上的某个位置（下次构建应用程序时，dSYM 目录将被覆盖）[1]

稍后，当您从客户那里得到崩溃报告时，您可以运行symbolicatecrashApple的脚本，将内存地址转换为函数名和行号。[2]

[1] Build->Archive 命令会自动执行此操作。
[2] 确切位置因 Xcode 版本而异，但它位于 Xcode.app 中的某个位置。
