当我的应用程序在模拟器或我的应用程序的临时版本中崩溃时，错误日志会详细并清楚地说明应用程序崩溃的位置。然而，一旦它被提交到应用商店并且我的用户正在使用它，我发现由谷歌分析和我自己的方法记录的错误日志正在编辑太多，以至于我无法判断错误发生在哪里。
如何确保在 ios prod 应用程序中生成并提交完整的错误日志？

我正在创建错误日志并将其保存到数据库中：
NSString *message=[exception debugDescription];
message = [message stringByAppendingString:@"\n\n*****REASON*****\n\n"];
message = [message stringByAppendingString:[exception reason]];
message = [message stringByAppendingString:@"\n\n*****NAME*****\n\n"];
message = [message stringByAppendingString:[exception name]];
message = [message stringByAppendingString:@"\n\n*****STACK TRACE*****\n\n"];
NSArray *ar = [exception callStackSymbols];
message = [message stringByAppendingString:[ar componentsJoinedByString:@"****"]];
id tracker = [[GAI sharedInstance] defaultTracker];
[tracker send:[[GAIDictionaryBuilder createExceptionWithDescription:message withFatal:@YES] build]];
