    <p>The views of <code>secondViewController</code> have not been loaded yet when you set them. You can verify this by querying for the value of <code>secondViewController.titleHeader</code> after pushing the view controller to the navigation stack.</p> <p>As a fix, you can declare a property in <code>secondViewController</code></p> <pre><code>@property (nonatomic, strong) NSString *titleHeaderText; </code></pre> <p>then set that property instead of <code>secondViewController.titleHeader setText</code><br> e.g.</p> <pre><code>secondViewController.titleHeaderText = [object name]; </code></pre> <p>After that, in your <code>secondViewController</code>'s <code>viewDidLoad</code> method, you can set the text of your label.</p> <pre><code>[self.titleHeader setText:self.titleHeaderText ]; </code></pre> <p><strong>EDIT:</strong><br> The behavior of <code>pushViewController</code> seems to have changed in iOS 7. I have tried and replicated your issue.</p> <p>If you do not want the above change, a workaround is by accessing the view of <code>secondViewController</code>, so that its views will be loaded before you call <code>label setText</code>.<br> e.g. </p> <pre><code>SecondViewController *secondViewController = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil code:[object code]]; [self.navigationController pushViewController:secondViewController animated:YES]; [secondViewController view]; [secondViewController.titleHeader setText:[object name]]; [secondViewController.headerView setBackgroundColor:colorHeaderGallery]; </code></pre>

Querying!

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).
