    NSMutableArray *all;
}
@synthesize mainTable;

{
    [super viewDidLoad];
    self.title = @"News";

    NSURL *url = [NSURL URLWithString:@"http://zacandcatie.com/YouTube/json.php"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    NSURLConnection *con = [[NSURLConnection alloc] initWithRequest:request delegate:self];
    [con start];
}

- (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:kNilOptions error:nil];
    for (int i =0; i < [news count]; i++)
    {
    NSIndexPath *indexPath = [self.mainTable indexPathForSelectedRow];
    title =[[news objectAtIndex:indexPath.row+i]objectForKey:@"title"];
        if (!all) {
            all = [NSMutableArray array];
        }
        [all addObject:title];
    }
    NSLog(@"%@",all);

    [mainTable reloadData];
}

You can do some thing like this :

- (UITableViewCell *)tableView:(UITableView *)tableView 
         cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    //  tableview cell setup

    NSArray* keys = [self.data allKeys];

    cell.textLabel.text = [self.data objectForKey:[keys objectAtIndex:indexPath.row]];

    return cell;
}

Please refer this links to have data in order in dictionary

NSDictionary with ordered keys

            [insert setObject:[info objectForKey:@"name"] forKey:@"name"];
            [insert setObject:[info objectForKey:@"city"] forKey:@"city"];
            [db insertDictionary:insert forTable:@"student_info"];

        }
    })

//.m file view....

-(void)viewDidAppear:(BOOL)animated
{
    NSString *qry=@"select * from student_info";
    ary=[[db lookupAllForSQL:qry] mutableCopy];
    [tableView reloadData];
}

Continuing @Divz Ans...

you will have create the .sqlite file. And there is nothing easier than this.

There are two ways(that i know) to create sqlite file,

1> you can download SQLite Manager add-on in firefox, where you can manipulate data in database graphically.

Or,

2> you can use Terminal with a single line command, sqlite3 dbFileName.sqlite. enter,

where you will get sqlite> now start with further SQL(create/insert/update..) queries.

you can find your sqlite file at MacHD>users>admin(not shared one)>yourFile.sqlite or, finder---go>home>yourFile.sqlite

-(void)InsertRecords:(NSMutableDictionary *)dict
{

sqlite3_stmt *stmt;
sqlite3 *cruddb;

NSMutableString *str = [NSMutableString stringWithFormat:@"Insert into tblName ("];

for (int i = 0; i<[[dict allKeys] count]; i++)
{
    [str appendFormat:@"%@,",[[dict allKeys] objectAtIndex:i]];
}
[str appendFormat:@")values ("];
for (int i = 0; i<[[dict allKeys] count]; i++)
{
    [str appendFormat:@"%@,",[dict valueForKey:[[dict allKeys] objectAtIndex:i]]];
}

[str appendFormat:@");"];
NSLog(@"qry : %@",str);
const char *sql = [str UTF8String]; ;

if((sqlite3_open([database UTF8String], &cruddb)==SQLITE_OK))
{
    if (sqlite3_prepare(database, sql, -1, &stmt, NULL) ==SQLITE_OK)
    {
        sqlite3_step(stmt);
        sqlite3_finalize(stmt);
    }
    else
    {
        NSLog(@"Problem with prepare statement: %s", sqlite3_errmsg(database));
    }
    sqlite3_close(database);
}
else
{
    NSLog(@"An error has occured: %s",sqlite3_errmsg(database));
}
}

Try this.

After parsing you data in the form of NSDictionary you can create a query of insert into and fire the query n your data will be save into your database
