objective c parsing returned json from wcf service

So I asked this question recently and I was able to make it work

objective c calling wcf rest service request

Here's my code

NSString *urlStringRequest = [NSString stringWithFormat:@"http://service.mydomain.com/UserAccountService.svc/UserLogin?id=%@&pword=%@", email, incPassword];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlStringRequest]];
    [request setHTTPMethod:@"GET"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

    NSError *error = nil;
    NSURLResponse *response = nil;
    NSData *result = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

    id jsonResult = [self parseJsonResult:result];

    NSLog(@"Json Result Woop: %@", jsonResult);

the parseJsonResult is exactly the same as the one that was on the link. My problem is though, whenever I would show the jsonResult on the NSLog, it would show the json result which is:

Json Result Woop: {
    Authenticated = 0;
    Message = "Invalid Log In.";
}

But I'm not really sure how I can go into the variable and retrieve the key and it's value one by one.

I tried to do this:

NSError *jsonParseError = nil;
NSMutableArray *jsonArray = [NSJSONSerialization JSONObjectWithData:result options:NSJSONReadingMutableContainers|NSJSONReadingAllowFragments error:&jsonParseError];
if(!jsonArray)
    NSLog(@"Parse error: %@", jsonParseError);
else
    for(NSDictionary *item in jsonArray)
        NSLog(@"%@", item);

using the result variable but it would just give me the keys.

Not really sure what to do.

JsonResult is already an NSDictionary as evidenced by NSLog showing it like this with curly braces. Just use 

jsonResult[@"Message"]

to get to the value for the Message key.
