    <p>I am brand new to iOS development, and I could not find a solution on here or Google, so I'm asking out of desperation.</p> <p>I have a class "ViewController" that is a subclass of UIViewController. In here, I have:</p> <pre><code>- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if ([self.bookTitle.text length] &gt; 0) self.entries = [self.bookLibrary searchForBook:self.bookTitle.text]; if ([segue.identifier isEqualToString: @"BookList"]) { TableViewController *controller = (TableViewController *)segue.destinationViewController; controller.itemCounter = [self.entries count]; controller.bookLibrary = [self.entries allValues]; } } </code></pre> <p>The view for this on the Storyboard has a connection to a Table View Controller that I dragged and dropped onto the grid. I clicked the "Table View Controller" at the bottom, and set my custom class "TableViewController" in the custom class input box.</p> <p>Now, from what I understand, the method above is passing all the data properly to the TableViewController. </p> <p>Here's one of the methods I have in the TableViewController</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *simpleTableIdentifier = @"BookCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier]; } Book* book = [self.bookLibrary objectAtIndex:indexPath.row]; cell.textLabel.text = book.title; NSLog(@"%@", book.title); return cell; </code></pre> <p>}</p> <p>The NSLog entry is printing out all the book titles to the console, so I know for a fact the data is being passed. However, when I run the program and click the button to pull up the Table View, it's just an empty table. Any hints? I can upload my entire project. Been at this for several hours and a bit frustrated. Please help :(</p> <p>EDIT: A response suggested I look at the state of my data variables in the table methods. It suggests their state is not what I think it is and that I should use NSLog to print out their values. I did just that, and I can see all the values printed out. I don't understand... they do infact have values assigned to them. The problem isn't that the data is missing.</p>

    1. COHave you updated the `- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section` function. With the number of cells to be displayed.

    3. COAlso, it may be just a typo but you've said that you have a ViewController class that's a subclass of UIViewController. However, if you're going to assign this class to a UITableViewController you dragged out, then it has to be a subclass of UITableViewController to match. If it's not, your class isn't going to get hooked up to the UITableView properly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
