Body
I have a <code>UINavigationController</code> with a visible Navigation Bar. I have one particular <code>UIViewController</code> which I'd like to hide the status bar when pushed into the navigation stack. Once this viewController is popped I'd like to show the status bar again. I'm hiding the bar in the <code>viewWillAppear</code> method of my <code>UIViewController</code> like this: <pre><code>- (void) viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [self.navigationController setWantsFullScreenLayout:YES]; [[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES]; } </code></pre> Note that I'm setting <code>setWantsFullScreenLayout:YES</code> here for clarity, but I'm actually just setting this property in Interface Builder. The problem: The navigation bar of the NavigationController doesn't move up to take the space of the now hidden status bar. A hacky solution The only thing I found that worked to refresh the position of the nav bar was to hide it and show it again, like this: <pre><code>[[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES]; [self.navigationController setNavigationBarHidden:YES animated:NO]; [self.navigationController setNavigationBarHidden:NO animated:NO]; </code></pre> but this is clearly a hack, there has got to be a better way. Other things I tried: <ol> <li>I tried calling the <code>[super viewWillAppear]</code> after hiding the status bar, i.e. at the end of my method.</li> <li>I tried setNeedsLayout on the navigationController.view like this: <pre><code>[[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES]; [self.navigationController.view setNeedsLayout]; </code></pre></li> </ol> but that doesn't seem to work. Any help appreciated. Thanks

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.
