c# - Monotouch Crashdump 缺少对我的代码的任何引用

Question

我有一个用 monotouch 编写的应用程序，我的一个(只有一个)用户应用程序崩溃了。我在崩溃转储上做了一个符号化。我在转储中看不到任何指向我的任何代码的东西:

关于我应该从这里做什么的任何建议？

iOS 崩溃日志在某些情况下没有描述性。

尝试替代 iOS 崩溃报告系统:

• 将用户操作记录到内存中；
• 订阅UnhandledException事件:

        // In AppDelegate.FinishedLaunching
        AppDomain.CurrentDomain.UnhandledException += (object sender, UnhandledExceptionEventArgs e) => {
            LogTool.SaveLog(e);
        };

• 当用户下次运行应用时，检查日志是否为空。如果是这样，建议用户通过电子邮件将崩溃日志发送给您(参见 MFMailComposeViewController 类使用示例)。

因此，您将获得解决问题所需的准确信息。
