    <p>In <strong>MainViewController.m</strong>, implement the <code>flipSideViewControllerDelegate</code> method as:</p> <pre><code> - (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller { self.nameField.text=controller.changeText.text; } </code></pre> <p>So when the <code>done:</code> method is called, this delegate method is also called with your <code>flipSideViewController</code> object as the argument, through which <code>changeText</code> can be accessed.</p> <p>EDIT to answer question in comment:</p> <p>In your protocol FlipSideViewControllerDelegate, add this method:</p> <pre><code> - (void)flipsideViewControllerDidSelect:(NSIndexPath*)indexPath </code></pre> <p>Then it is similar to the other delegate method implementation in <strong>MainViewController.m</strong> , which is how the protocol works really. If your MainViewController conforms to the protocol, it can implement methods of that protocol. By default all the methods declared in the protocol are optional, but you have the option to specify if the method is optional or required by using</p> <pre><code>@optional //list of methods @required //list of methods </code></pre> <p>Bear in mind that if your a method is declared as required in the protocol, any class conforming to that protocol <strong>must</strong> implement it. Anyway, in your <strong>MainViewController.m</strong>:</p> <pre><code>- (void)flipsideViewControllerDidSelect:(NSIndexPath*)indexPath { int anInt=indexPath.row; self.nameField.text=[NSString stringWithFormat:@"%d",anInt]; } </code></pre>

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.
