Parse WordPress JSON into UITableView on iOS

I’m trying to parse a JSON from this URL, which is a JSON output from WordPress. For some reason, there’s no output in the UITableView.

Here’s the code I have got to parse. I’m sure I’m missing out something but I’m not able to figure out how to parse Nested JSON in this code.

ViewController.m:

    - (void)viewDidLoad
{
    [super viewDidLoad];
    self.title = @"News";

    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;

    NSURL *url = [NSURL URLWithString:@"http://www.karthikk.net/?json=1"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [[NSURLConnection alloc] initWithRequest:request delegate:self];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    data = [[NSMutableData alloc] init];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)theData
{
    [data appendData:theData];
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;

    news = [NSJSONSerialization JSONObjectWithData:data options:nil error:nil];
    [mainTableView reloadData];
}

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    UIAlertView *errorView = [[UIAlertView alloc] initWithTitle:@"Error" message:@"The download could not complete - please make sure you're connected to either 3G or Wi-Fi." delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
    [errorView show];
    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
}

- (int)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (int)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [news count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MainCell"];

    if(cell == nil){
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"MainCell"];
    }

    cell.textLabel.text = [[news objectAtIndex:indexPath.row] objectForKey:@"title"];
    cell.detailTextLabel.text = [[news objectAtIndex:indexPath.row] objectForKey:@"date"];

    return cell;
}

ViewController.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController {
    IBOutlet UITableView *mainTableView;

    NSArray *news;
    NSMutableData *data;
}

@end

Please help me out in paring this.

Thanks much! I’ve tried referring to multiple threads on Stackoverflow, but all failed to work for me.

P.S.: I’m a newbie to iOS App Development. And I’m using this Video tutorial to mess with the code.
