iOS - Symbolicate Stack trace symbols

Question

I want to symbolicate the stack trace symbols logged using [NSThread callStackSymbols] to identify the full stack backtrace calls. But, this doesn't give symbolicated trace.

I tried this with development as well as enterprise build. Neither worked out. Is there anyway to symbolicate this? I searched lot of forums and all are asking to do this with atos command like below

atos -arch armv7 -o 'app name.app'/'app name' 0x000000000

But, I am not sure whats the memory address i have to use for the above command and how to get it.

Any help would be greatly appreciated, thanks.

Answer 1

There's a few pieces you're skipping here. The memory addresses in atos should reference the load address and the stack address, and you'll need the dSYM file as well.

There's actually a very good writeup on apteligent called Symbolicating an iOS Crash Report about doing this manually. I would suggest reading it thoroughly to understand how symbolication works.
