trouble with parsing json

i'm new in the iphone and json world . i have this json structure . You can see it clearly by putting it here http://jsonviewer.stack.hu/ .

 {"@uri":"http://localhost:8080/RESTful/resources/prom/","promotion":[{"@uri":"http://localhost:8080/RESTful/resources/prom/1/","descrip":"description
 here","keyid":"1","name":"The first
 name bla bla
 ","url":"http://localhost/10.png"},{"@uri":"http://localhost:8080/RESTful/resources/promo/2/","descrip":"description
here","keyid":"2","name":"hello","url":"http://localhost/11.png"}]}

i want to parse it with json-framework . I tried this

 NSDictionary *json    = [myJSON JSONValue];
            NSDictionary *promotionDic    = [json objectForKey:@"promotion"];
            NSLog(@" res %@ : ",[promotionDic objectAtIndex:0]);

But then how to do to get for exemple , the name of the object at index 0 ? I think i should put object in an NSArray ? but i dont find how :/ and i dont the number of object is variable . Help please .

Solution

  • The JSON says:

    ..."promotion":[{"@u...

    That "[" there means that "promotion" is keyed to an array, not a dictionary.

    So really your code should be:

    NSDictionary *json    = [myJSON JSONValue];
NSArray *promotions   = [json objectForKey:@"promotion"];
NSLog(@"res: %@",[promotions objectAtIndex:0]);
