JSON parsing in iOS 6 issues - ios

Question

I am trying to parse some values from a json. I manage to get the value for results.geometry.location. If the parameters fails the server return a json with 2 value. results which is empty[] and status "some error".
url = [NSString stringWithFormat:#"http://maps.googleapis.com/maps/api/geocode/json?address=%#&sensor=false",postalCode];
NSData *jsonDataString = [[NSString stringWithContentsOfURL:[NSURL URLWithString:url] encoding:NSUTF8StringEncoding error: nil] dataUsingEncoding:NSUTF8StringEncoding];
NSArray* myResults = [NSJSONSerialization JSONObjectWithData:jsonDataString options:NSJSONReadingMutableContainers | NSJSONReadingMutableLeaves error:&error];
latLon =[myResults valueForKeyPath:#"results.geometry.location"];
generalDict = (NSDictionary *)[latLon objectAtIndex:0];
NSLog(#"%#",[generalDict objectForKey:#"lat"]);
It's confusing. I tried:
latLon =[myResults valueForKeyPath:#""];
generalDict = (NSDictionary *)[latLon objectAtIndex:0];
NSLog(#"%#",[generalDict objectForKey:#"status"]);
but is not working. How can I get the value of the status. This is how it looks like when the request is invalid:
{
"results" : [],
"status" : "ZERO_RESULTS"
}

myResults is a dictionary, not an array. I think you want something like this:
NSURL *url = [NSURL urlWithString:[NSString stringWithFormat:#"http://maps.googleapis.com/maps/api/geocode/json?address=%#&sensor=false",postalCode];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[NSURLConnection sendAsynchronousRequest:request
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
NSDictionary *jsonPayload = [NSJSONSerialization JSONObjectWithData:data
options:NSJSONReadingMutableContainers | NSJSONReadingMutableLeaves
error:nil];
NSString *status = [jsonPayload objectForKey:#"status"];
//Check for error status
NSArray *resultsArray = [jsonPayload objectForKey:#"results"];
//Do whatever you want with your results array
}];
