Launching in Landscape Mode

Applications in iPhone OS normally launch in portrait mode to match the orientation of the Home screen. If you have an application that runs in both portrait and landscape modes, your application should always launch in portrait mode initially and then let its view controllers rotate the interface as needed based on the device’s orientation. If your application runs in landscape mode only, however, you must perform the following steps to make it launch in a landscape orientation initially.

• In your application’s Info.plist file, add the UIInterfaceOrientation
  key and set its value to the
  landscape mode. For landscape
  orientations, you can set the value
  of this key to
  UIInterfaceOrientationLandscapeLeft
  or
  UIInterfaceOrientationLandscapeRight.

• Lay out your views in landscape mode and make sure that their autoresizing options are set correctly.

• Override your view controller’s shouldAutorotateToInterfaceOrientation: method and return YES only for the
  desired landscape orientation and NO
  for portrait orientations.
