Example data:

NSString *strData = @"{\"1\": {\"name\": \"Jerry\",\"age\": \"12\"}, \"2\": {\"name\": \"Bob\",\"age\": \"16\"}}";
NSData *webData = [strData dataUsingEncoding:NSUTF8StringEncoding];

NSError *error;
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:webData options:0 error:&error];
NSLog(@"JSON DIct: %@", jsonDict);

NSLog output:

JSON DIct: {
     1 =     {
         age = 12;
         name = Jerry;
     };
     2 =     {
         age = 16;
         name = Bob;
     };
}
