在iOS崩溃报告中获取线程特定信息？

我使用下面的代码从我的iOS应用程序中获得的崩溃报告：在iOS崩溃报告中获取线程特定信息？

void *frames[128]; 
int i,len = backtrace(frames, 128); 
char **symbols = backtrace_symbols(frames,len); 

NSMutableString *buffer = [[NSMutableString alloc] initWithCapacity:4096]; 

NSBundle *bundle = [NSBundle mainBundle]; 
[buffer appendFormat:@"PComp version %@ build %@\n\n", 
    [bundle objectForInfoDictionaryKey:@"CFBundleVersion"], 
    [bundle objectForInfoDictionaryKey:@"CIMBuildNumber"]]; 
[buffer appendString:@"Uncaught C++ Exception\n"]; 
[buffer appendString:@"Stack trace:\n\n"]; 
for (i = 0; i < len; ++i) { 
    [buffer appendFormat:@"%4d - %s\n",i,symbols[i]]; 
}

这只会提供有关当前线程的信息？我怎么能得到这个所有线程的堆栈跟踪？
