How to get an array of JSON objects from NSData object [duplicate]

So I'm using an HTTP GET method which returns an array of JSON objects, which are stored in NSData. The array looks like this:

[{"created_at":"2013-03-09T04:55:21Z","data_type":"image","id":5354,"latitude":37.785834,"longitude":-122.406417,"name":"tempObject","privacy":"public","radius":1000.0,"updated_at":"2013-03-09T04:55:21Z","user_id":101},{"created_at":"2013-03-10T20:57:08Z","data_type":"image","id":5364,"latitude":37.785834,"longitude":-122.406417,"name":"tempObject","privacy":"public","radius":1000.0,"updated_at":"2013-03-10T20:57:08Z","user_id":101}]

How would I go about extracting these JSON objects and iterate through them from the NSData?

If you're using iOS 5.0 and up, you can do this:

Objective-C:

NSError *error = nil;
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:myNSData options:kNilOptions error:&error];

if (error != nil) {
    NSLog(@"Error parsing JSON.");
}
else {
    NSLog(@"Array: %@", jsonArray);
}

Swift:

do {
    let jsonArray = try JSONSerialization.jsonObject(with: myNSData, options:[])
    print("Array: \(jsonArray)")
}
catch {
    print("Error: \(error)")
}
