我有用户发邮件给我堆栈跟踪当我的应用程序在他们的设备上的崩溃。 在此之前的iOS 6，他们是这样的：

从的CoreFoundation等方法名，并询问发生了什么用户，我可以得到的事故发生，其中一个不错的主意。
然而，由于iOS 6的发布，我崩溃报告都这个样子：

我从这里的堆栈跟踪，这将提示用户该应用程序被重新打开时，发送电子邮件至：
void uncaughtExceptionHandler(NSException *exception) {
//make a file name to write the data to using the documents directory:
NSString *fileName = [NSString stringWithFormat:@"%@/crashlog.txt", documentsDirectory];
//create content - four lines of text
NSString *content = [NSString stringWithFormat:@"CRASH: %@ (%@)\n\nTRACE: %@", [exception name], [exception reason], [exception callStackSymbols]];
//save content to the documents directory
[content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil];
}
如果没有方法名，这是有害无益。 有没有让这些方法名回到我的堆栈跟踪的方法吗？ 这是一个版本的配置，不能进行调试。
编辑：
我已按照说明这个答案 。
我提取.app和.dSYM从文件.xcarchive包和运行atos -arch armv7 -o 'MyApp.app'/'MyApp'
不过，我仍然没有从获得方法名atos 。
