    <p>I've followed the tutorial below, it basically just tells you to create a button and a label. When you click the button the label should change to some text.</p> <p><a href="http://paulpeelen.com/2011/03/17/xcode-4-ios-4-3-hello-world/" rel="nofollow">http://paulpeelen.com/2011/03/17/xcode-4-ios-4-3-hello-world/</a></p> <p>It runs but it shows a blank screen. When you click the screen it goes blue like the entire page is a button. I think it's loading the mainwindow.xib file instead of the default ViewController.xib</p> <p>Any ideas, I'm obviously missing something?</p> <p>Thanks</p> <p>EDIT</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @interface fun_buttonViewController : UIViewController { UILabel *textLabel; } @property (nonatomic, retain) IBOutlet UILabel *textLabel; - (IBAction)changeTheTextOfTheLabel; @end </code></pre> <p>The implementation:</p> <pre><code>#import "fun_buttonViewController.h" @implementation fun_buttonViewController @synthesize textLabel; - (void)dealloc { [super dealloc]; [textLabel release]; } - (IBAction)changeTheTextOfTheLabel { [textLabel setText:@"Hello, World!"]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } #pragma mark - View lifecycle /* // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; } */ - (void)viewDidUnload { [super viewDidUnload]; // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return (interfaceOrientation == UIInterfaceOrientationPortrait); } @end </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.
