    <p>Check to make sure that you've correctly set the identifier for the table cell.</p> <p>To do this, open up your storyboard editor and go to your table view. Click on the prototype cell and open up the Utilities pane. Check that "Identifier" is "ClassCell".</p> <p>Next, make sure your ViewController is a UITableViewController and implements the UITableViewDelegate protocol. It's not clear if you've done this.</p> <p>Your ScheduleTableViewController.h should be something like:</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @interface ScheduleTableViewController : UITableViewController &lt;UITableViewDelegate&gt; // code @end </code></pre> <p>Also, I noticed this here:</p> <pre><code>NSMutableArray *classes = [[NSMutableArray alloc]init]; Course *class = [[Course alloc]init]; [class setName:@"AP Psychology"]; [class setRoom:@"E203"]; [class setTeacher:@"Juiliette Forbes"]; [classes addObject:class]; [class setName:@"AP Literature"]; [class setTeacher:@"Kristen Holtz"]; [class setRoom:@"E207"]; [classes addObject:class]; [class setName:@"AP Physics"]; [class setTeacher:@"Peter Dalby"]; [class setRoom:@"D205"]; [classes addObject:class]; </code></pre> <p>Since *class is a pointer to a course object, you've only actually created one, then you keep editing its properties and re-adding it to the array. Create multiple class objects like so:</p> <pre><code>Course *class1 = [[Course alloc] init]; // set properties Course *class2 = [[Course alloc] init]; // set properties Course *class3 = [[Course alloc] init]; // set properties [classes addObjects:class1, class2, class3, nil]; </code></pre>

    1. COMy reuse identifier is good and so is my delegate protocol. I think it has less to do with my array and more to do with my table as when I attempted to add text that wasn't from the array still nothing appearred. Thank you for the suggestion about the class pointer. I thought the same thing but the man in the video was able to do it with a single pointer reused over and over.

    2. COWhat Vinodh is referring to when he says not to redeclare your datasource array is that you have twice typed: NSMutableArray *classes; You only need to declare something once. Therefore, change the following line: NSMutableArray *classes = [[NSMutableArray alloc]init]; to: classes = [[NSMutableArray alloc]init]; (Edit: What this means is that your array is not filling with anything because it hasn't been initialised. Instead you've initialised another variable called the same thing.)

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.
