NSLog - Strange behavior

Question

I found that last word showed with double quotes. But why?

NSDictionary *guide2 = [NSDictionary dictionaryWithObjectsAndKeys:kArr, @\"Kate\", aArr, @\"Ana-Lu         


        

Answer 1

It seems that because of the special character - in the key Ana-Lucia, it displays it within double-quotes. May be this is because to show that the key is a single word. If your key contains only alphabets like "AnaLucia", then it will display it without quotes.

The key is displayed in double-quotes if it contains any characters other than alphabets, even if it is an underscore(_) or space.
