JSONValue ARC issue

Question

Im trying to use the built in JSON framework in iOS5, but i get an ARC issue when trying to compile this code:

NSDictionary *results = [jsonString JSONValue]         


        

Answer 1

The message you get means 'There is no method JSONValue declared in NSString' (which is absolutely true). In order to use the built in JSON serializer try this one:

NSError *error;
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *results = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];

Ps For options see the documentation on NSJSONSerialization class. Also note that results can be an NSArray as well.
