NSException callStackSymbols

Question

When exception occurred there is stack trace this kind:

2 CoreFoundation 0x013bd1cc -[__NSArrayI objectAtIndex:] + 236
3 –ò–°–≠–î 0x0000ac76 -[ContentButton handleGesture:] + 326
4 UIKit 0x00de24f2 -[UIGestureRecognizer _updateGestureWithEvent:] + 730
...

I see that exception occurred when I try to get objectAtIndex: in NSArray in my custom class ContentButton in handleGesture: method.

But what does this numbers after message mean (like +236)?

In java stack trace that mean line number where exception occurred (as I know). but message [__NSArrayI objectAtIndex:] sent in line 47 (not 236).

Thanks a lot.

+236 means the offset in bytes from the beginning of the method in the binary. — VenoMKO, May 03 '17 at 11:12

There's a great video from WWDC 2010 on understanding crash reports.

You can find it here (login to Apple Developer required)

Still don't know what does this numbers means. In video was told that XCode symbolises any crash reports by self, but is not - still get +236-like appends to messages name and still don't know what is this.. – Gusev Andrey Sep 26 '11 at 06:24
@GusevAndrey I'm confused, too. As far as I can tell, it's the number of line numbers down from the declaration of the method _in the assembly code_. Not terribly helpful unless you know precisely how every line of your class translates to Assembly, and how the compiler associated variables. – Ky - Jul 28 '15 at 15:05
