Getting warning in iPhone: NSString may not respond to '-JSONValue'

Question

In my iPhone app, I am making an access to the webserver to fetch the data.

Here I am using JSON to retrieve the data from database.

I get a warning that says:

NSString may not respond to '-JSONValue'

How to resolve it?

Answer 1

Add this #import "JSON.h" at the top of your .m or .h file.

Answer 2

Have you tried to add JSON Library to your project and import it

#import "JSON/JSON.h"

Answer 3

You probably just miss the include to your JSON library
