    <p><strong>Setting custom background for UINavigationBar to support iOS5 and iOS4 too!</strong></p> <p><strike><a href="http://www.mladjanantic.com/setting-custom-background-for-uinavigationbar-what-will-work-on-ios5-and-ios4-too/" rel="nofollow noreferrer">http://www.mladjanantic.com/setting-custom-background-for-uinavigationbar-what-will-work-on-ios5-and-ios4-too/</a></strike></p> <p><a href="http://rogchap.com/2011/06/21/custom-navigation-bar-background-and-custom-buttons/" rel="nofollow noreferrer">http://rogchap.com/2011/06/21/custom-navigation-bar-background-and-custom-buttons/</a></p> <hr> <p>As you know, until iOS 5 came out, we used <code>drawRect</code> override in <code>AppDelegate</code> to customize <code>UINavigationBar</code>. But know, iOS 5 give us some new method for styling (and old doesn’t work).</p> <p>How to build app that will work on iOS 4 and iOS 5 with stylized <code>UINavigationBar</code>?</p> <p>You must to do both!</p> <p>In <code>AppDelegate</code> use this code:</p> <pre><code>@implementation UINavigationBar (UINavigationBarCategory) - (void)drawRect:(CGRect)rect { UIImage *img = [UIImage imageNamed:@"navbar.png"]; [img drawInRect:rect]; } @end </code></pre> <p>and in <code>viewDidLoad</code> method for iOS5 (in your view implementation):</p> <pre><code>if ([self.navigationController.navigationBar respondsToSelector:@selector( setBackgroundImage:forBarMetrics:)]){ [self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"navbar.png"] forBarMetrics:UIBarMetricsDefault]; } </code></pre> <p>If you see, here we are asking if navbar will respondToSelector to avoid crash on iOS4! </p>

    1. COThis is a bit different solution. In this solution, you should always set up Navigation bar for each viewController. but for iOS4 and iOS5 support. It's a bit better

    2. COI put the code in my AppDelegate. Every ViewController has the image in the NavigationBar. It seems that you have to implement it only one time and not in EVERY ViewController :-)

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
