Xcode selecting JSON array objects

Question

I have an NSDictionary that is getting a JSON file. This is my JSON file:

{
"People": {
    "Downtown": [
        {
            "firstName": "Steve",
            "lastName": "Smith",
            "Color": "Blue",
        },
        {
            "firstName": "John",
            "lastName": "Doe",
            "Color": "Red",
        }

      ]
}
}

In Xcode I used a NSLog to display the whole file and it works, but now I would like to call on for example the second object in the JSON array and extract the last name giving me the value "Doe" allowing me to put it in a NSString in Xcode.

I tried

NSLog(@"This is in dictionary: %@", [dictionary objectForKey: @"People"]);

in Xcode, witch got me closer but still pretty far. I'm thinking it's something along the lines of –objectForKey:, but Im pretty new to NSDictionary so I don't know all the syntax or how to use it properly.

NSLog(@"Dict:%@",[[[[Dict valueForKey:@"People"] valueForKey:@"Downtown"] valueForKey:@"lastName"] objectAtIndex:1]);

Hope it helps.

it looks to me you put the array at wrong location. the `Downtown` has the array not the `lastName`, I guess. – holex Jul 11 '14 at 14:43

Try This:

NSLog(@"This is in dictionary: %@", [dictionary valueForKeyPath: @"People"]);
NSLog(@"This is in dictionary: %@", [dictionary valueForKeyPath:@"People.Downlotwn.Firstname"]);

etc

If you are getting null, try to remove Key: People at start.
