我是靠谱客的博主仁爱紫菜，最近开发中收集的这篇文章主要介绍ios 捕抓crash_Xamarin.ios 手动捕获到的crash符号化的问题，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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。

public classApplication

{//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);

}

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：

System.Reflection.TargetInvocationException: An exception occurred during the operation, making the result invalid. Check InnerException for exception details. ---> System.TimeoutException: The operation has timed out.

这个是真机中捕获到的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。
