As far as I can tell, this problem arises because the UITabBarController and UINavigationController are returning their own default values for -(BOOL)shouldAutorotate and -(NSUInteger)supportedInterfaceOrientations. One solution is to extend both of those classes via categories (or just subclass), in order to return the appropriate values from your own implementations of these methods in your view controller. This is what worked for me (you can just drop this into your App Delegate): <pre><code>@implementation UITabBarController(AutorotationFromSelectedView) - (BOOL)shouldAutorotate { if (self.selectedViewController) { return [self.selectedViewController shouldAutorotate]; } else { return YES; } } - (NSUInteger)supportedInterfaceOrientations { if (self.selectedViewController) { return [self.selectedViewController supportedInterfaceOrientations]; } else { return UIInterfaceOrientationMaskAllButUpsideDown; } } @end @implementation UINavigationController(AutorotationFromVisibleView) - (BOOL)shouldAutorotate { if (self.visibleViewController) { return [self.visibleViewController shouldAutorotate]; } else { return YES; } } - (NSUInteger)supportedInterfaceOrientations { if (self.visibleViewController) { return [self.visibleViewController supportedInterfaceOrientations]; } else { return UIInterfaceOrientationMaskAllButUpsideDown; } } @end </code></pre> By default, all your view controllers will continue to autorotate. In the two View Controllers that should only support portrait mode, implement the following: <pre><code>-(BOOL)shouldAutorotate { return NO; } -(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskPortrait; } </code></pre>

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.
