From our previous applications we know that we can accomplish this by performing a quick orientation change within the Awake() method of our application:

function Awake()
{
  iPhoneSettings.screenOrientation = iPhoneScreenOrientation.Landscape;
}

In previous examples we put our functions in the Start() method, but we are putting this call in the Awake() method. The reason for this is that we want this script, and the orientation settings, to be processed as soon as the scene is loaded, but before the joystick script tries to determine where to put the joysticks. If we didn't do this the position of the joysticks would be too close together as their positions would have been derived from the portrait orientation.

If you were to run your application now you would find that the application will hold to a single screen orientation, however, when you rotated you would get a black outline that rotates with the screen. This black outline represents the iOS keyboard interface rotating with the device. To prevent this from happening you need to lock the keyboard so that it is in the same orientation with the application.

void Awake()
{
  iPhoneSettings.screenOrientation = iPhoneScreenOrientation.Landscape;
  iPhoneKeyboard.autorotateToPortrait = false;
  iPhoneKeyboard.autorotateToPortraitUpsideDown = false;
}
