충돌 로그의 자세한 내용 Xamarin.iOS

Question

내 테스트 비행 사용자 한 명이 앱을로드 할 때마다 충돌이 발생합니다. 테스트 장치 나 시뮬레이터에서이를 재현 할 수 없었습니다.

나는 충돌 보고서를 작성했으며이 파일을 완전히 상징화했다고 생각합니다. 다음은 blog입니다.

그러나 나는 내 코드로 다시 오류를 매핑 할 수 없습니다 :

는 사람이 올바른 방향으로 날 포인트?

Answer 1

우리가 테스터에게 조사하도록 요청한 응용 프로그램을 충돌시키는 예외를 추적하는 방법은 iOS의 전역 예외 처리기에 연결하여 정보를 IO에 기록하는 클래스를 사용하는 것입니다.

등급 :하여 'FinishedLaunching'방법으로 다음을 수행하여 AppDelegate.cs의 글로벌 처리되지 않은 이벤트에

using System; 
using System.IO; 
using UIKit; 

namespace namespace.TestingLogs 
{ 
    public static class ApplicationLog 
    { 
     private static string _filename = "LogFile-"; 

     public static void CreateFile(string SessionFilename) 
     { 
      _filename += SessionFilename; 

      var docs = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments); 
      var filename = Path.Combine(docs, _filename); 
      var Device = UIDevice.CurrentDevice; 
      File.AppendAllText(filename, ("======Device Information======" + Environment.NewLine)); 
      File.AppendAllText(filename, ("Battery Level: " + Device.BatteryLevel + Environment.NewLine)); 
      File.AppendAllText(filename, ("Model: " + Device.Model + Environment.NewLine)); 
      File.AppendAllText(filename, ("System Version: " + Device.SystemVersion + Environment.NewLine)); 
      File.AppendAllText(filename, ("[" + DateTime.UtcNow.ToString() + "]" + "======Start Log======" + Environment.NewLine + Environment.NewLine)); 
      Console.WriteLine("[] = " + filename); 
     } 

     public static void AppendFile(string appendText) 
     { 
      var txt = Environment.NewLine + appendText; 

      var docs = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments); 
      var filename = Path.Combine(docs, _filename); 
      File.AppendAllText(filename, txt); 
     } 
    } 

    public class ExitAppException : Exception 
    { 
     public ExitAppException() { } 
     public ExitAppException(string message) : base(message) { } 
     public ExitAppException(string message, Exception inner) : 
     base(message, inner) 
     { } 
    } 
} 

후크 :

 AppDomain.CurrentDomain.UnhandledException += (object sender, UnhandledExceptionEventArgs e) => 
     { 
      try 
      { 
       //Record the error in our application logs 

       ApplicationLog.AppendFile(
        DateTime.Now.ToString() + " : " + "[CRITICAL GLOBALLY HANDLED EXCEPTION] - Critical exception has been hit! - Message: " + e.ExceptionObject + 
         Environment.NewLine + Environment.NewLine + 
          "========= Critcal Error has been hit, application closed =========" + 
           Environment.NewLine + Environment.NewLine 
        ); 
      } 
      catch (Exception genEx) 
      { 
       var Error = genEx.Message; 
      } 
     }; 

사용 분명히 어떤 표현에 가장 적합한 당신을. 우리가하는 방식 대신 문자열 작성기를 사용하는 것이 좋습니다. 그러나 일반적인 개념은 같습니다. 그런 다음 사용자는 'macgo iphone explorer'(무료) 응용 프로그램 문서 폴더에 액세스 할 수있는 로그 파일을 다운로드 할 수 있습니다. 그러면 로그 파일이 전자 메일로 전송됩니다. 희망이 조금 도움이됩니다.
