Body
I gave an app with say 10 view controllers. I use navigation controller to load/unload them. All but one are in portrait mode. Suppose the 7th VC is in landscape. I need it to be presented in landscape when it gets loaded. Please suggest a way to force the orientation go from portrait to landscape in IOS 6 (and it will be good to work in IOS 5 as well). Here is how I was doing it BEFORE IOS 6: <pre><code>- (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; UIViewController *c = [[[UIViewController alloc]init] autorelease]; [self presentModalViewController:c animated:NO]; [self dismissModalViewControllerAnimated:NO]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{ return (interfaceOrientation == UIInterfaceOrientationPortrait); } </code></pre> Presenting and dismissing a modal VC was forcing the app to review its orientation, so <code>shouldAutorotateToInterfaceOrientation</code> was getting called. What I have have tried in IOS 6: <pre><code>- (BOOL)shouldAutorotate{ return YES; } -(NSUInteger)supportedInterfaceOrientations{ return UIInterfaceOrientationMaskLandscape; } - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{ return UIInterfaceOrientationLandscapeLeft; } </code></pre> On load, the controller keeps staying in portrait. After rotating the device, the orientation changes just ok. But I need to make the controller to rotate automatically to landscape on load, thus the user will have to rotate the device to see the data correctly. Another problem: after rotating the device back to portrait, the orientation goes to portrait, although I have specified in <code>supportedInterfaceOrientations</code> only <code>UIInterfaceOrientationMaskLandscape</code>. Why it happens? Also, NONE of above 3 methods are getting called. Some (useful) data: <ol> <li>In my plist file I have specified 3 orientations - all but upside down.</li> <li>The project was started in Xcode 4.3 IOS 5. All classes including xibs were created before Xcode 4.5 IOS 6, now I use the last version.</li> <li>In plist file the status bar is set to visible.</li> <li>In xib file (the one I want to be in landscape) the status bar is "None", the orientation is set to landscape.</li> </ol> Any help is appreciated. Thanks.

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.
