    <p>I'm customizing the elements like navigation bar, tab bar and uibarbuttonitem using UIAppearance. It works very well except for a very strange behavior of the UIBarButtonItem elements. On the top level of the navigation controller hierarchy everything looks good, but if I push the next view controller, the UIBarButtonItem elements move a little bit downwards, but at the same time, the back button stays at its correct position. I attached two images to illustrate my problem.</p> <p><strong>1) First view controller in the navigation controller hierarchy</strong></p> <p><img src="https://i.stack.imgur.com/ucVWD.png" alt="enter image description here"></p> <p><strong>2) Second view controller in the navigation controller hierarchy</strong></p> <p><img src="https://i.stack.imgur.com/lZCIs.png" alt="enter image description here"></p> <p><strong>EDIT: The code</strong></p> <pre><code> //Change navigation bar appearance [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"GPNavigationBarBackground.png"] forBarMetrics:UIBarMetricsDefault]; [[UINavigationBar appearance] setShadowImage:[[UIImage alloc] init]]; [[UINavigationBar appearance] setShadowImage:[UIImage imageNamed:@"GPNavigationBarShadow.png"]]; [[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys: [UIColor whiteColor], UITextAttributeTextColor, [UIFont boldSystemFontOfSize:17], UITextAttributeFont,nil]]; [[UINavigationBar appearance] setTitleVerticalPositionAdjustment:2.f forBarMetrics:UIBarMetricsDefault]; UIImage *buttonBackground = [[UIImage imageNamed:@"GPNavigationBarButton.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 10, 0, 10)]; UIImage *buttonPressedBackground = [[UIImage imageNamed:@"GPNavigationBarButtonPressed.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 10, 0, 10)]; UIImage *backButtonBackground = [[UIImage imageNamed:@"GPNavigationBarBackButton.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 15, 0, 10)]; UIImage *backButtonPressedBackground = [[UIImage imageNamed:@"GPNavigationBarBackButtonPressed.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 15, 0, 10)]; [[UIBarButtonItem appearance] setBackgroundImage:buttonBackground forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; [[UIBarButtonItem appearance] setBackgroundImage:buttonPressedBackground forState:UIControlStateHighlighted barMetrics:UIBarMetricsDefault]; [[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonBackground forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; [[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonPressedBackground forState:UIControlStateHighlighted barMetrics:UIBarMetricsDefault]; [[UIBarButtonItem appearance] setBackButtonBackgroundVerticalPositionAdjustment:1.f forBarMetrics:UIBarMetricsDefault]; [[UIBarButtonItem appearance] setBackgroundVerticalPositionAdjustment:1.f forBarMetrics:UIBarMetricsDefault]; [[UIBarButtonItem appearance] setTitlePositionAdjustment:UIOffsetMake(0, 1.f) forBarMetrics:UIBarMetricsDefault]; </code></pre>

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.
