Xamarin.ios 手动捕获到的crash符号化的问题

悬赏园豆:40 [待解决问题]

ios设备产生的crash文件根据Archives或者dSYM文件符号化成可识别的内容网上很多,但是这里要问的不是这个。因为app只是内部系统,并没有放到Appstore中,因此不能使用Appstore的crash收集功能。于是叫客户手动获取crash并发给我们。一开始客户还是愿意手动把crash给过来的,但是后面开始嫌麻烦,让我们做自动上传的功能。但是ios貌似是不允许app操作crash文件的,于是就有了下面的代码出现,自己手动捕获。废话不多说,上代码。

复制代码
public class Application
    {
        // This is the main entry point of the application.
        static void Main (string[] args)
        {
            // if you want to use a different Application Delegate class from "AppDelegate"
            // you can specify it here.
            try {
                UIApplication.Main(args, null, "AppDelegate");
            } catch (Exception ex) {
                string documents = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
                string filename = Path.Combine(documents, "myCrash.txt");
                string splitString = "#split#";
                string content = ex.ToString() + splitString + DateTime.Now.ToString() + splitString + (LoginInfo.wUserCName ?? "")
                    + splitString + (LoginInfo.wVersion ?? "");
                File.WriteAllText(filename, content);
            }
        }
    }
复制代码

简单粗暴,确实能捕获到一些有用信息(只能捕获到主线程的,因此如果子线程有可能会crash的操作,对子线程try/catch,并在catch中BeginInvokeOnMainThread把exception throw 出来)。全局捕获异常并记录下来,下次打开app的时候通过wcf上传到DB中。然而,调试环境下产生完全可读的错误,在真机中却是会有部分未符号化的内容。

这个是调试环境捕获到的crash:

眼尖的你们应该能发现那些未被符号化的东东了,这就是我这里要提问的问题:如何把这些基址和偏移符号化。网上找的最接近的应该就是说用xcode自带的atos,但我试过这个貌似还是符号化不了。

有没有对这方面比较了解的前辈指导下。
