how to Json request convert to native object or list?

{
"id": "1",
"result": [
{
"Name": "John",
"Statu": "Online"
},
{
"Name": "Alex",
"Statu": "Online"
},
{
"Name": "Diaz",
"Statu": "Offline"
}
]
}

How do i extract each "car" JSON object and put it into a native object? I tried several way but i can't do that.

    NSString *responseString = [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease];

       NSString *responseDict = [responseString JSONValue]; 

       NSArray *objects = [NSArray arrayWithObjects:[responseDict valueForKeyPath:@"result.Name"],[responseDict valueForKeyPath:@"result.Statu"],nil];
       NSLog(@"objects Array: %@",objects);



     **==> NSLOG gives:
                      (
                        (
                        "John",
                        "Alex",
                        "Diaz"
                        ),
                        (
                        "Online",
                        "Online",
                        "Offline"
                        )
                      )



    NSArray *resultsArray = [responseString JSONValue];

     for (NSDictionary *personDict in resultsArray) 
        {

       NSLog(@"ihaleAdi =: %@",[carDict valueForKey:@"result.ihaleAdi"]);

       NSLog(@"ihaleDurum =: %@",[carDict valueForKey:@"result.Statu"]);

       }

Use an Array to capture the responseString:

NSString *responseString = [request responseString];
NSArray *array = [responseString JSONValue];

Then when you need an individual item from that array use a Dictionary:

// 0 is the index of the array you need
NSDictionary *itemDictionary = (NSDictionary *)[array objectAtIndex:0];

Given a JSON responseString that looks like this:

[{"UniqueID":111111,"DeviceName":"DeviceName1","Location":"Device1Loc","Description":"Device1Desc"},{"UniqueID":22222,"DeviceName":"DeviceName2","Location":"Device2Loc","Description":"Device2Desc"}]

You will wind up with an Array that looks like this:

myArray = (
        {
        Description = "Device1Desc";
        DeviceName = "DeviceName1";
        Location = "Device1Loc";
        UniqueID = 111111;
    },
        {
        Description = "Device2Desc";
        DeviceName = "DeviceName2";
        Location = "Device2Loc";
        UniqueID = 222222;
    }
)

And a Dictionary of index 0 that looks like this:

myDictionary = {
    Description = "Device1Desc";
    DeviceName = "DeviceName1";
    Location = "Device1Loc";
    UniqueID = 111111;
}

Sorry for any confusion and improperly instantiated object earlier. I am still a relative newbie that learned something today.
