The UIImagePickerController class supports portrait mode only.

Ahogy a dokumentacioban is all:

Important: The UIImagePickerController class supports portrait mode only. This class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified, with one exception. In iPhone OS 3.1 and later, you can assign a custom view to the cameraOverlayView property and use that view to present additional information or manage the interactions between the camera interface and your code.
