    <p>I'm developping an app for iOS 4.2+. I subclassed my <code>UINavigationController</code> to insert two <code>UIImageView</code> and make the navigation bar look custom. Everything is working great but I have a little problem. I created custom <code>UIBarButtonItem</code> and inside my view controllers i put them with :</p> <pre><code>self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:backButton]; </code></pre> <p>It works too but the problem is that to make this work I need to call it from:</p> <pre><code> - (void)viewDidAppear:(BOOL)animated ; </code></pre> <p>So it only appears after the animation and I can see the non customized button 1 second before the customized one replace it.</p> <p>(I tried with <code>viewWillAppear</code> but then nothing append in navigationbar)</p> <p>I would like to know if you have a solution that could correct this problem.</p> <p>PS: I never use IB, everything is made programmatically.</p> <p>Thanks from France !</p> <p>EDIT 1: here is the code that didn't show anything for <code>viewWillAppear</code>:</p> <pre><code>- (void)viewWillAppear:(BOOL)animated { [self setTitle:@"Jeu"]; //Bouton testflight TIFButton *testFeedbackButton = [[TIFButton alloc]init]; [testFeedbackButton setTitle: @"Envoyer un Feedback" forState:UIControlStateNormal]; [testFeedbackButton addTarget:self action:@selector(launchFeedback) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *testFeedback = [[UIBarButtonItem alloc] initWithCustomView:testFeedbackButton]; self.navigationItem.rightBarButtonItem = testFeedback; TIFBackButton *backButton = [[TIFBackButton alloc]init]; [backButton setTitle: @"Retour" forState:UIControlStateNormal]; [backButton addTarget:self action:@selector(popToPrecedentViewController) forControlEvents:UIControlEventTouchUpInside]; self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:backButton]; } </code></pre>

    1. COIt *should* work with `viewWillAppear`, but your `backButton` view needs to be instantiated / created before you assign `self.navigationItem.leftBarButtonItem`.

    2. COWhy do you need to call it from viewDidAppear? Why doesnt't it work from viewDidLoad?

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.

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