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.

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