As you can see in the NSException (http://developer.apple.com/documentation/Cocoa/Reference/Foundation/Classes/NSException_Class/Reference/Reference.html#//apple_ref/doc/uid/20000061) class reference there is no direct way to do this. If the object raising the exception chooses to it can include this information in the userInfo dictionary.

You can use the stackReturnAddresses (http://developer.apple.com/documentation/Cocoa/Reference/Foundation/Classes/NSException_Class/Reference/Reference.html#//apple_ref/occ/instm/NSException/callStackReturnAddresses) to work out this sort of information, although this would take some work. Fortunately this work has been done for you as described in the documentation (http://developer.apple.com/documentation/Cocoa/Conceptual/Exceptions/Tasks/ControllingAppResponse.html#//apple_ref/doc/uid/20000473).

So, in short, read the documentation (in this case the obviously named Exception Programming Topics for Cocoa (http://developer.apple.com/documentation/Cocoa/Conceptual/Exceptions/Exceptions.html#//apple_ref/doc/uid/10000012)). The answer is almost always there.

Thanks for your reply. it really helped me lot.
I printed stack trace and it is giving me class file and its line number.
but i want all stack trace printed in string value.

Just capture the output of the NSTask. I'm not about to Google that for you.
