ios Simulator not displaying my titles

In the video "Adding a Table View Controller class" Admit sets up the app to display the blog titles. But form some reason my simulator is not displaying the titles. Here is my code

TableViewController.m

#import "TableViewController.h"

@interface TableViewController ()

@end

@implementation TableViewController

- (id)initWithStyle:(UITableViewStyle)style
{
    self = [super initWithStyle:style];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.titles = [NSArray arrayWithObjects:@"The Missing Widget In the Android SDk: SmartImageView",
                  @"Get started with ios Development",
                  @"An Interveiw with Shay Howe",
                  @"Treehouse Friends: Paul Irish",
                  @"Getting A Job In Web Design and Development",
                  @"Treehouse Show Eposide 13 – LLJS, Navicons and Freamework Flights",
                  nil];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    return [self.titles count];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

    // Return the number of rows in the section.
    return 0;
}

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

    cell.textLabel.text = [self.titles objectAtIndex:indexPath.row];

    return cell;
}

I made sure to give the cell the identifier as cell not sure this is happening.

Thanks

here you have:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    //this will give you a lot of sections in the tableview. Im not sure how the table is supposed to be set up but you most likely only want 1 section with the title rows inside that section
    return [self.titles count];
}

and in:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

    // Return the number of rows in the section.
    //this causes you to have 0 rows, so nothing gets displayed in the table at all
    return 0;
}

these are causing your problems. You most likely want one section with all your titles in that section, so try :

- (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 self.titles.count;
}
