    <p>I'm working on a tab bar application and one of the tabs has a UISearchDisplayController hooked up to a UISearchBar. It's all connected up in the NIB and is working. When I tap the search bar, the Scope and Cancel buttons fly in etc, and the search delegate updates the results table correctly.</p> <p>However, I'm trying to implement the same code in the <code>viewDidLoad</code> message instead of the NIB, however when I delete the search display controller from the NIB and uncomment my code to create the same controller in the function, it doesn't work. It's as if there's some fundamental connection not being made so that all my search delegate functionality isn't being called.</p> <p>Here's my <em>working</em> NIB version of the Search Display Controller. It's hooked up to the search bar, the <code>UINavigationController</code> subclass (<code>MASearchController</code>) and the root view of that is hooked up as the <code>searchContentsController</code>.</p> <p><a href="http://img192.imageshack.us/img192/3050/screenshot20100307at304.png">alt text http://img192.imageshack.us/img192/3050/screenshot20100307at304.png</a></p> <p>Now this is what you would expect to do in code to create the same, right? What I'm doing is leaving the UISearchBar in the NIB to eliminate one piece of the puzzle at a time in code.</p> <pre><code>// [MASearchController viewDidLoad] UISearchDisplayController *searchController = [[[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:[[self viewControllers] objectAtIndex:0]] autorelease]; [searchController setDelegate:self]; [searchController setSearchResultsDelegate:self]; [searchController setSearchResultsDataSource:self]; </code></pre> <p>I've checked all objects at run time and they all check out. Essentially I've deleted the search display controller from the NIB and then put in the code to create it in the <code>viewDidLoad</code> message.</p> <p>Why would this not work? The search keyboard comes up but none of my search and button animation functionality work???</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.
