i'm just looking for a confirmation here.  if i'm getting this crash:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFString appendString:]: nil argument'

is it definitely crashing on my NSMutableString appendString: method or is it possible it's also crashing on NSString stringByAppendingString:? as far as i know either one will throw an exception that's why i'm asking. thank you,

If you're wondering whether that exact message is specific to one of the two cases, why not try both and find out?

[[NSMutableString string] appendString:nil]; // What message do you get?

    [@"" stringByAppendingString:nil];  // What message do you get now?
