    <p>I have a UIViewController that returns <code>YES</code> in <code>shouldAutorotateToInterfaceOrientation:</code> for <code>UIDeviceOrientationPortrait</code> and <code>NO</code> for everything else. With that view on the top of the stack, I use <code>pushViewController:animated:</code> to push a new <code>UIViewController</code>. The new controller returns <code>YES</code> for anything in <code>shouldAutorotateToInterfaceOrientation:</code>.</p> <p>The first view refuses to rotate (as expected). Once the second view is pushed, the user can rotate the device and the UI will rotate (also as expected). If the second view is in landscape mode and the user presses the back button (which calls <code>popViewControllerAnimated:</code>), the first view will appear rotated (<strong>unexpected!</strong>).</p> <p>If the user rotates the device back to portrait orientation, the view will rotate and then be stuck in portrait mode as before. This works but it's ugly for the user until they rotate back. So I'm in search of a way to make this view stay in portrait mode.</p> <p>The only workaround I have found so far is to use <code>-[UIDevice setOrientation:]</code>, which throws a warning (<code>orientation</code> is read-only) but works since it is actually defined. This is a huge hack and I'd like a real solution. In search of a real solution I attached GDB to the Photos application (MobileSlideshow.app) and discovered that it too uses <code>-[UIDevice setOrientation:]</code>. Being an internal application though I guess they have different rules.</p> <p>Is there a correct way to achieve the expected autorotation behavior?</p>

    1. COI believe there are examples of apps that (presumably) use setOrientation in the app store. One is Tweetie, which can force a landscape keyboard when writing tweets. Maybe they got away with it since it's not the default settings.

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.
