    <p><strong>Note:</strong> </p> <p>See accepted answer (not top voted one) for solution as of iOS 4.3.</p> <p>This <strong>question</strong> is about a behavior discovered in the iPad keyboard, where it refuses to be dismissed if shown in a modal dialog with a navigation controller. </p> <p>Basically, if I present the navigation controller with the following line as below:</p> <pre><code>navigationController.modalPresentationStyle = UIModalPresentationFormSheet; </code></pre> <p>The keyboard refuses to be dismissed. If I comment out this line, the keyboard goes away fine. </p> <p>...</p> <p>I've got two textFields, username and password; username has a Next button and password has a Done button. The keyboard won't go away if I present this in a modal navigation controller.</p> <p><strong>WORKS</strong></p> <pre><code>broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; [self.view addSubview:b.view]; </code></pre> <p><strong>DOES NOT WORK</strong></p> <pre><code>broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:b]; navigationController.modalPresentationStyle = UIModalPresentationFormSheet; navigationController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:navigationController animated:YES]; [navigationController release]; [b release]; </code></pre> <p>If I remove the navigation controller part and present 'b' as a modal view controller by itself, it works. Is the navigation controller the problem?</p> <p><strong>WORKS</strong></p> <pre><code>broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; b.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:b animated:YES]; [b release]; </code></pre> <p><strong>WORKS</strong></p> <pre><code>broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:b]; [self presentModalViewController:navigationController animated:YES]; [navigationController release]; [b release]; </code></pre>

    2. CO+1 Thank you for your great explanation. But where do I have to put that method? It seems not working where I create the code for presenting the model controller...

    3. COIt has to be in the modal view controller class itself.

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.
