    <p>You don't see anything happened because you create <strong>new instance</strong> of label and do not add it anywhere. If you really want to add new label to your view then create it with appropriate frame and actually add it to some view, e.g.</p> <pre><code>-(void)setOne:(NSMutableArray *)theArray { label1 = [[UILabel alloc] initWithFrame:CGRectMake(10.0f, 10.0f, 200.0f, 30.0f)]; label1.text = @"Test"; [self.view addSubview: label1]; // And do not forget to release your label! [label1 release]; } </code></pre> <p>If you want to change text of label that already exists do not create new instance in your method, just set new text to it:</p> <pre><code>-(void)setOne:(NSMutableArray *)theArray { // if label1 already exists we don't need to create a new one label1.text = @"Test"; } </code></pre> <p><strong>Edit:</strong> (from more info in comments)</p> <p>When you create view controller it may not load its view immediately so in your code</p> <pre><code>FirstViewController *FVC = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil]; [FVC setOne:[resultaten objectAtIndex:indexPath.row]]; </code></pre> <p>when you call setOne method fvc's view may still not be loaded and label1 is still nil in that method. You can solve that forcing controller's view to load, the following should work:</p> <pre><code> FirstViewController *FVC = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil]; FVC.view; [FVC setOne:[resultaten objectAtIndex:indexPath.row]]; </code></pre> <p>But in general I'd suggest to store your values in some class that's independent from UI (i.e. Model) or at least in separate variable of your controller and set it to UI elements only when they actually loaded or appear on screen (in viewDidLoad or viewWillAppear methods)</p>

    1. COThank you, but this solution does not work. When I tried it, the UILabel did not changed.

    2. CO@Jelle how you create your label? if you add it using IB make sure it is properly connected to some IBOutlet in your view controller (make sure it is not nil in setOne method)

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.
