Using Foursquare's API to get venues into an NSArray

I'm trying to save venues into a NSArray. Venue is an array in an NSDictionary Response. I would like an NSArray with all the venues so I can populate a table.

NSURL *url = [[NSURL alloc] initWithString:@"https://api.foursquare.com/v2/venues/search?ll=40.7,-74&query=dog&limit=10"];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
    NSDictionary *responseData = [JSON objectForKey:@"response"];
    self.venues = responseData[@"venues"];

    [self.tableView setHidden:NO];
    [self.tableView reloadData];
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
    NSLog(@"Request Failed with Error: %@, %@", error, error.userInfo);
}];
[operation start];

Four squares partial

response: {
    venues: [{
        id: "4ea2c02193ad755e37150c15"
        name: "The Grey Dog"
        contact: {
            phone: "+12129661060"
            formattedPhone: "+1 212-966-1060"
        }
        location: {
            address: "244 Mulberry St"
            crossStreet: "btwn Spring & Prince St"
            lat: 40.723096
            lng: -73.995774
            distance: 2595
            postalCode: "10012"
            city: "New York"
            state: "NY"
            country: "United States"
            cc: "US"
        }

You do not need a new array to hold all the Venues.

First create a global NSDictionary like:

NSDictionary* venuesDict;

@property (nonatomic, retain) NSDictionary* venuesDict;

and synthesise it. You can then assign it in you code above like so:

venuesDict = [[JSON objectForKey:@"response"] objectForKey:@"venues"];
NSLog(@"%@", venuesDict); //everything should work up to here!

Presuming the NSLog prints the output as you posted in you question (but with venues as the first object), you can populate a table like this:

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // Return the number of rows in the section.
    return [[venuesDict objectForKey:@"venues"] count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    cell.textLabel.text = [[venuesDict objectForKey@"venues"] objectForKey:@"name"];

    return cell;
}
