    <p>Good morning.</p> <p>I have been working through a lot of tutorials the past year, and have seen several methods of passing reference back up the View Hierarchy with Storyboards. I was wondering what some best practices are, and more importantly any pitfalls using the following methods:</p> <ol> <li><p>Protocol - the child view implements a protocol, that the parent view sets itself as the delegate to and responds to messages. This can be used to pass back information to the delegate. The Child does not need to know anything about the reason it was called, it does it's job, and sends back whatever information it was asked for.</p></li> <li><p>Public property of the Child ViewController that has the model reference. On the segue you retrieve the reference to the destination view Controller. This view controller has the model property exposed publically. You pass in your reference to the model. I personally like this method - can't see any real pitpalls with it. then when the child makes changes the model is changed directly. at the point <code>[self.navigationController dismissViewControllerAnimated:YES]</code> gets called to or however you navigate off/dismiss the view controller you have the information in the model you want.</p></li> <li><p>ANYTHING ELSE? - someone else has a good idea, i'd love to hear it.</p></li> </ol> <p>Thanks for anyone's input on this. I know there are always more than 1 way to skin a cat, I just want to skin the cat cleanly and quickly. (-Sorry cat)</p> <p>Steve</p>

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.
