iOS 5UIViewController

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

By default, this method returns YES for the UIInterfaceOrientationPortrait orientation only.

iOS 6UIViewController

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

By default, this method returns YES for the UIInterfaceOrientationPortrait orientation only.

The default implementation of this method returns the app’s default set of supported interface orientations, as defined in the UIInterfaceOrientation key of the Info.plist file.

If the file does not contain that key, this method returns all interface orientations for the iPad idiom and returns all interface orientations except the portrait upside-down orientation for the iPhone idiom.

おまけ

おまけ• 複数法対応のViewControllerをモーダルで出す時、初期方向を変えたい

• 例：動画プレイヤー縦横対応しているが、初期では横にしたい。
