    <p>All you need do is implement the UITableViewDelegate and UITableViewDatasource methods required for the level of table view functionality you require. These methods can be in any class(es) though said classes should conform to the relevant protocols. The delegate and datasource should be set on the UITableView instance - either programatically or with Interface Builder. According to the docs you <strong>will</strong> lose some functionality - see the <a href="http://developer.apple.com/IPhone/library/documentation/UIKit/Reference/UITableViewController_Class/Reference/Reference.html#//apple_ref/doc/uid/TP40007523-CH3-DontLinkElementID_1" rel="nofollow noreferrer">overview section</a>.</p> <p>Personally I find that many developers seem to be obsessed with providing all of this functionality in a single monolithic view controller class, and that because they have a table view in their view then a subclass of UITableViewController must be used. However, I like to consider the <a href="http://en.wikipedia.org/wiki/Single_responsibility_principle" rel="nofollow noreferrer">Single Responsibility Principle</a> and will often break the datasource and delegate into separate classes when the complexity is anything other than simple. The code is also then not tied to a specific UIViewController implementation.</p> <p>In situations where I have separate datasource/delegate classes I often construct and wire them up to the table view using Interface Builder and not in code. This approach (to me at least) is in the spirit of <a href="http://en.wikipedia.org/wiki/Dependency_Injection" rel="nofollow noreferrer">Dependency Injection</a> and saves writing some boiler-plate code, and provides some level of <a href="http://en.wikipedia.org/wiki/Decoupling#Software_Development" rel="nofollow noreferrer">decoupling</a>.</p> <p>These choices of course are influenced by the complexity of the functionality that you are trying to achieve - for simple implementations I might find myself using UITableViewController.</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.
