    <p>My app runs in a UINavigationController. When I push in a new view controller from the right, the top right UIBarButtonItem (Edit) shifts down by 1 pixel — the Edit button stays in place, but the graphic noticeable shifts down. </p> <p>I've noticed this only happens after I set up a UIAppearance proxy for the bar button item. This is my code for doing that:</p> <pre><code>UIImage *barButton = [[UIImage imageNamed:@"navBarBarButton"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 5)]; [[UIBarButtonItem appearance] setBackgroundImage:barButton forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; </code></pre> <p>navBarBarButton.png is a 52x31 bar button image. </p> <p>Other potentially relevant info:</p> <ul> <li>This only happens in the iOS 6 simulator — it's fine in iOS 5.</li> <li>This app uses storyboards, and the pushes are handled by segues. </li> <li>The one-pixel displacement only happens once, i.e. it doesn't get pushed down a second time when I go another level into a navigation controller.</li> <li>The Edit button's text stays where it is; only the button graphic moves. </li> <li>I tried starting the app in a different view controller (i.e. the second in the navigation stack). The bar button item shows up at the normal (higher) position, then shifts downwards when I push in a new view. This seems to suggest it's not related to any specific view controller.</li> </ul> <p>Has anyone seen this, know why this is happening, or how to prevent the button from shifting? Thanks.</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.
