Create Data Model for JSON - IOS / Objective-C

I am developing an IOS application in Objective-C, in which I call the URL to retrieve an array of JSON objects (restaurants). I want to analyze them on an objective-C Model . Using them to populate on a UICollectionView that I already developed. My task requires me to design this model to store Json objects and then use them to populate on a UICollectionView. I do not know how to achieve this in Objective-C, please help me with this. The resulting JSON is as follows.

"restaurants" : [
{
    "name": "Burger Bar",
    "backgroundImageURL": "http://somthing.com/Images/1.png",
    "category" : "Burgers",
        "contact": {
            "phone": "1231231231",
            "formattedPhone": "(123) 123-1231",
            "twitter": "1twitter"
        },
        "location": {
            "address": "5100 Belt Line Road, STE 502",
            "crossStreet": "Dallas North Tollway",
            "lat": 32.950787,
            "lng": -96.821118,
            "postalCode": "75254",
            "cc": "US",
            "city": "Addison",
            "state": "TX",
            "country": "United States",
            "formattedAddress": [
                "5100 Belt Line Road, STE 502 (Dallas North Tollway)",
                "Addison, TX 75254",
                "United States"
            ]
        }
},
{
    "name": "seafood Kitchen",
    "backgroundImageURL": "http://somthing.com/Images/2.png",
    "category": "Seafood",
        "contact": {
            "phone": "3213213213",
            "formattedPhone": "(321) 321-3213",
            "twitter": "2twitter"
        },
        "location": {
            "address": "18349 Dallas Pkwy",
            "crossStreet": "at Frankford Rd.",
            "lat": 32.99908456526653,
            "lng": -96.83018780592823,
            "postalCode": "33331",
            "cc": "US",
            "city": "Dallas",
            "state": "TX",
            "country": "United States",
            "formattedAddress": [
                "18349 Dallas Pkwy (at Frankford Rd.)",
                "Dallas, TX 75287",
                "United States"
            ]
        }
}

]

The code below shows how to call a URL and retrieve and print JSON parsing objects.

NSString *urlString = @"http://somthing.com/Images/collection.json";
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[NSURLConnection sendAsynchronousRequest:request
                                   queue:[NSOperationQueue mainQueue]
                       completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
                           if (!error) {
                               NSError* parseError;
                               id parse = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&parseError];  
                               NSLog(@"%@", parse);
                           }
                       }];
