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?
