objective c - Description of NSDictionary - why are some key names with quotes? -

i used simple nslog on dictionary

nslog(@"dict %@", dictionary);

why key names in "quotes" , not?

when string has characters apart alphabets + numerics, quote string. basic methodology of description function.

objective-c cocoa nsdictionary
