ios - Parse JSON in Objective C

Question

I have this json returned from a cms and I need to break it apart and use the different values.

{"nodes":
     [{"node":
        {"created":"14012013165204","lastupdated":"03042013133901","type":"News"}
     }]
}

I use JSONKit framework and here is my code:

    NSString* theURL = [NSString stringWithFormat:@"http://testserver.com/content_lastupdate.json"];
    NSError* err = nil;
    NSURLResponse* response = nil;
    NSMutableURLRequest* request = [[NSMutableURLRequest alloc] init];
    NSURL*URL = [NSURL URLWithString:theURL];
    [request setURL:URL];
    [request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
    [request setTimeoutInterval:30];
    NSData* data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

    NSString *output = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    NSDictionary *resultsDictionary = [output objectFromJSONString];

    NSLog([NSString stringWithFormat:(@"Response: %@"), output]);

    NSDictionary *nodes = [resultsDictionary objectForKey:@"nodes"];
    NSObject *node = [nodes objectForKey:@"node"];

I do not know how to get the next part of the results. nodes key is found but the next one is not. Any idea what basics I'm missing here?

"nodes" is an array. Try this one:

NSArray *nodes = resultsDictionary[@"nodes"];
NSDictionary *node = nodes[0];
node = node[@"node"]
