what's the disadvatage of callStackSymbols

Question

In the article Reliable Crash Reporting,Landon Fuller said it's better not to use [NSThread callStackSymbols],but can i use [exception callStackSymbols] when i want to get the full symbolic call stack and send it to my server?

Answer 1

They get their stack the same way, but the timing is different - NSThread one will get you the callstack at the time you send the callStackSymbols message, and the NSException one will get you the symbols at the time the exception occurred.
