How to fix a No visible @interface for NSString declares the selector JSONValue error

Question

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?

You probably need to import the `NSString+SBJSON.h` file in the .m file containing the code you posted. — rmaddy, Nov 13 '12 at 16:52

Add this line to the top of your .m file, where you try to call it:

#import "NSString+SBJSON.h"
