Information not being displayed on table view ?

- (void)viewDidLoad {
    [super viewDidLoad];

    NSURL *blogURL = [NSURL URLWithString:@"http://blog.teamtreehouse.com/api/get_recent_summary/"];

    NSData *jsonData = [NSData dataWithContentsOfURL:blogURL];

    NSError *error = nil;

    NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];

    self.blogPosts = [dataDictionary objectForKey:@"posts"];


- (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 1;

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    // Return the number of rows in the section.
    return [self.blogPosts count];

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    //creating a cell object that can be reused
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];

  //creating a NSDicationary object for the cells
    NSDictionary *blogPost = [self.blogPosts objectAtIndex:indexPath.row];

    //setting the text of the cell and retrieving the titles from the NSDictionary
    cell.textLabel.text = [blogPost valueForKey:@"Title"];
    //setting the detailed text of the cell and reteiveing the authors of the NSDictionary
    cell.detailTextLabel.text = [blogPost valueForKey:@"Author"];

    //returning the cell object
    return cell;

You seem to be making the same mistake as I did.

cell.textLabel.text = [blogPost valueForKey:@"Title"]; cell.detailTextLabel.text = [blogPost valueForKey:@"Author"];

Change the uppercase in "Title" and "Author" to "title" and "author" and that should hopefully solve your problem.
