    <p><strong>ADDED:</strong> I see that my question is viewed often without upvotes so I decided that you guys do not get what you search. Redirecting you to question that has really nice answer about <a href="https://stackoverflow.com/questions/12662240/how-to-make-app-fully-working-correctly-for-autorotation-in-ios-6">How to handle orientation changes in iOS6</a></p> <p>Specific demands to orientation changes: <a href="https://stackoverflow.com/questions/15947349/how-to-handle-different-orientations-in-ios-6">Restricted rotation</a></p> <p>Upvotes are welcome :)</p> <hr> <p>I've created a new project from Master Detail template and trying to start it with landscape orientation. As you know the </p> <p><code>- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation</code> </p> <p>method is deprecated and we must use </p> <p><code>- (NSUInteger)supportedInterfaceOrientations</code> </p> <p>and/or </p> <p><code>- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation</code></p> <p>Here's my code:</p> <pre><code>- (NSUInteger)supportedInterfaceOrientations { NSLog(@"supported called"); return UIInterfaceOrientationMaskAll;//Which is actually a default value } - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation { NSLog(@" preferred called");//This method is never called. WHY? return UIInterfaceOrientationLandscapeRight; } </code></pre> <p>As you can see I'm trying to return landscape orientation in preferred method but it is never called. p.s. documentation states:</p> <blockquote> <p>Discussion The system calls this method when presenting the view controller full screen. You implement this method when your view controller supports two or more orientations but the content appears best in one of those orientations.</p> <p>If your view controller implements this method, then when presented, its view is shown in the preferred orientation (although it can later be rotated to another supported rotation). If you do not implement this method, the system presents the view controller using the current orientation of the status bar.</p> </blockquote> <p>So, the question is: Why the prefferredOrientation method is never get called? And how should we handle different orientations in different controllers?. Thanks! P.S don't mark the question as duplicate. I've investigated all similar questions and they do not have answer for mine.</p>

    1. COYou can follow Apple's tutorial for same [Supporting Multiple Interface Orientations](http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/RespondingtoDeviceOrientationChanges/RespondingtoDeviceOrientationChanges.html) Hope this will help you out.

    2. COFrom your link: "When a view controller is presented over the root view controller, the system behavior changes in two ways. First, the presented view controller is used instead of the root view controller when determining whether an orientation is supported. Second, the presented view controller can also provide a preferred orientation. If the view controller is presented full screen, the user interface is presented in the preferred orientation." That's what I'm doing....or I just do not understand them..explain please in more details..

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.
