    <p>I had the same problem and here is the solution that worked for me. Say you're pushing <code>SomeUIViewController</code> onto your navigation stack.</p> <p>Define this (private) ivar in the interface of <code>SomeUIViewController</code>:</p> <pre><code>// keep a reference to the navigation controller for use in viewDidDisappear:(BOOL)animated method UINavigationController * _navigationController; </code></pre> <p>Implement the following methods of <code>SomeUIViewController</code>:</p> <pre><code>- (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; // here, your controller still has a reference to self.navigationController _navigationController = [self.navigationController retain]; } - (void)viewDidDisappear:(BOOL)animated { // at this point, self.navigationController = 0x0, so // use your retained reference to the navigation controller to perform any last minute operations, then release [_navigationController setToolbarHidden:YES]; [_navigationController release]; [super viewDidDisappear:animated]; } </code></pre> <p>The idea is that you want to hide the toolbar owned by the navigation controller <em>after</em> <code>SomeUIViewController</code>'s view has disappeared. This way, you avoid any unwanted display artifacts.</p> <p><strong>DISCLAIMER</strong></p> <p>This is merely an answer that shows a workaround solution for the stated question. It is meant solely to point out a detail of the inner workings of the framework. It is also meant as an example of what <em>not</em> to submit to the Apple AppStore.</p>

Guidance
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.
