I have encountered this error:
No visible @interface for 'NSString' declares the selector 'JSONValue'.
The error occurs on:
NSDictionary * root = [responseString JSONValue];
NSArray *data = [root objectForKey:@"data"];
does anyone know how to fix it? Could I be missing a JSON file?

Install the NSString+JSON category.
