    <p>Ok, there is quite a bit of confusion in the answers already given here...</p> <p>First, you're correct to not call <code>[super loadView];</code>, see <a href="http://developer.apple.com/library/ios/documentation/UIKit/Reference/UIViewController_Class/Reference/Reference.html#//apple_ref/doc/uid/TP40006926-CH3-SW1" rel="nofollow"><code>- (void)loadView</code></a>:</p> <blockquote> <p>If you override this method in order to create your views manually, you should do so and assign the root view of your hierarchy to the view property. (The views you create should be unique instances and should not be shared with any other view controller object.) Your custom implementation of this method should not call super.</p> </blockquote> <p>If you really mean to use <code>loadView</code> (i.e. creating your view programmatically, and not from a NIB), then in your implementation you <em>must</em> assign the <code>view</code> property of your controller.</p> <p>Also, you do not need to retain your button the way you're using it, because you're adding it as a subview of your main view (your main view will own it after that).</p> <p>Based on these considerations, your method would look like this:</p> <pre><code> -(void)loadView { CGRect frame = [[UIScreen mainScreen] applicationFrame]; // adjust to your needs UIView *rootView = [[UIView alloc] initWithFrame:frame]; UIButton *chooseSubjectButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; chooseSubjectButton.frame = CGRectMake(15.0f, 205.0f, 296.0f, 51.0f); [chooseSubjectButton addTarget:self action:@selector(chooseSubject) forControlEvents:UIControlEventTouchUpInside]; [rootView addSubview:chooseSubjectButton]; self.view = rootView; [rootView release]; } </code></pre> <p>Of course, if you use a NIB to define your root view, you need to override <code>-viewDidLoad:</code> for additional configuration.</p> <p>Hope this helps.</p>

    1. COyour suggestion about `[super loadView]` seems wrong. Please read the doc clearly.

    2. COi think you did not get what the apples documentation has to offer please go through it again for clearing your concepts. you dont call the super loadview method it is called automatically by the view controller class; i think this is what you meant to say, because if you dont write the super loadView then in that case if you add the views like label, buttons etc then their will be no view present in which these controls can be added and ultimately you will see your application being crashed.

    3. COThank you octy. Your explanation finally makes sense to me. I'm now going to join the "your custom implementation of this method should not call super" camp.

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).
