从CoreFoundation等方法名称,并询问用户发生了什么,我可以得到一个很好的想法,在哪里崩溃发生.

但是,由于iOS 6已经发布,我的崩溃报告如下所示：

CRASH: NSRangeException (*** -[__NSArrayI objectAtIndex:]: index 2147483670 beyond bounds [0 .. 11])

我从这里获取堆栈跟踪,当应用程序重新打开时,用户被提示通过电子邮件发送：

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];
}

没有方法名称,这比无用的更糟.有没有办法让这些方法名回到我的堆栈跟踪？这是一个发布配置,而不是调试.

编辑：

我按照this answer的指示.

我从.xcarchive包中提取.app和.dSYM文件,并运行atos -arch armv7 -o’MyApp.app’/’MyApp’

但是,我还没有从atos获取方法名称.
