    <p><strong>update 2</strong></p> <p><code>viewDidAppear</code> is executed twice, once before and once after, the overlay button is touched. Would a fix be to add a conditional to <code>viewDidAppear</code> which would return control to the calling class? If so, I would appreciated suggestions. Or maybe the very fact that <code>viewDidAppear</code> execute twice suggests another approach to a fix?</p> <p><strong>update 2</strong></p> <p><strong>update 1</strong></p> <p>Maybe the problem is my usage of <code>viewDidAppear</code> and <code>viewDidLoad</code> shown below. Can anyone help, please?</p> <pre><code>- (void)viewDidAppear:(BOOL)animated { self.overlayViewController = [[BSsetupOverlayViewController alloc] initWithNibName:@"BSsetupOverlayViewController" bundle:nil] ; // as a delegate we will be notified when pictures are taken and when to dismiss the image picker self.overlayViewController.delegate = self; [self showImagePicker:UIImagePickerControllerSourceTypeCamera]; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view from its nib. } </code></pre> <p><strong>update 1</strong></p> <p><strong>update 0</strong></p> <p>Perhaps I was not clear that the difference between the version that does not work and the one that does is that Storyboard is used in the one that does not work. Why would a <code>done</code> button work without Storyboard, but not with, even though only a nib is involved with the overlay?</p> <p><strong>update 0</strong></p> <p><a href="https://stackoverflow.com/questions/15623754/camera-overlay-picture/">The UIButton here</a> was able to dismiss the camera preview, but in my actual app, tapping the UIButton only temporarily dismisses the preview and overlay screen. Immediately the preview returns. I think the problem is with the way I am implementing the delegate to the UIImagePicker, but I may be wrong.</p> <p><a href="http://schott.selfip.net/~brian/" rel="nofollow noreferrer">I have created <code>setup.zip</code> here</a> which contains a sample project with the undesirable behavior.</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.
