    <p>I'm very new with Xcode and I would like to find a way to display something different if the user is logged in to my app or if he is not.</p> <p>I have a tabbed application. The authenticated user should access directly to the tabbed views. But the user that is not should land on an authentication page.</p> <p>My guess is that I need to have something like :</p> <pre><code>if (user) { // Do stuff if user logged in. } else { // Display the authentication page. } </code></pre> <p>But I have no idea on how to accomplish that and I didn't find anything about that. I'm looking for hints.</p> <p>EDIT:</p> <p>My question is not about how I could know if a user is authenticated or not, but how I can display a specific page in a case and an other page in an other case.</p> <p>Where and how should I write the code, knowing that I already know how to distinguish an authenticated user : </p> <pre><code> if (user is authenticated) { // SHOW FIRSTVIEWCONTROLLER } else { // SHOW SECONDVIEWCONTROLLER } </code></pre> <p>EDIT 2:</p> <p>I have a tabbed application, with 3 tabs and a mainstoryboard (no xibs). I want to add a page, before the tabbed pages, where the user can authenticate.</p> <p>So I need to display this viewController on a condition. If the user is not authenticated I show the page, if he is I show directly the tabbed pages.</p> <p>Again, I don't want to know how to distinguish if the user is authenticated or not, I just wan't to know how I can display a ViewController if a condition is fulfilled.</p>

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).
