    <p>Generally you will start with the Template called "Tab Bar Application" and as of Xcode 4 starts by loading the MainWindow Nib, which hold a tab bar and the tab bar is set up in IB to have 2 view controllers, called "FirstViewController", and "SecondViewController"...</p> <p>You can follow that pattern if it suites you, otherwise you may want to start with a view based application and add your own tab bar. I personally find it to be easier to control the tab bar, through the <code>UITabBarDelegate</code>, especially if you plan to do anything slightly esoteric.</p> <p><strong>Edit:</strong></p> <p>Basically one of two ways, if you plan to load a Navigation controller stack, or a single modal view.</p> <p>1)</p> <pre><code>ThirdViewController * controller = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil]; UINavigationController * myNavigationController = [[UINavigationController alloc] initWithRootViewController:controller]; [self presentModalViewController:myNavigationController animated:YES]; [controller release]; [myNavigationController release]; </code></pre> <p>2)</p> <pre><code>ThirdViewController * controller = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil]; [self presentModalViewController:controller animated:YES]; [controller release]; </code></pre> <p>either way get back to the Tab environment by calling the following on the view controller that is calling present modal.</p> <blockquote> <p>[self dismissModalViewControllerAnimated:YES];</p> </blockquote>

    1. COIf you had to transtition from the first or secondviewController to another controller where would you call it? In the rootTabBarController?

    3. COBut for example, imagine I have a TabBarController, there are tabs which are named AViewController, BViewcontroller and CViewController. If I want for instance that when i touch a button in AViewController to show another view what's the best way to do so? Calling the view inside AViewController or sending a selector to the root TabBarController and calling it there? By the way, i read that I should never subclass a UITabBarController, how am I suspose to do it?

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.
