Please read the docs for UIImagePickerViewController:

The table indicates that on iPad, if you specify a source type of UIImagePickerControllerSourceTypePhotoLibrary or UIImagePickerControllerSourceTypeSavedPhotosAlbum, you must present the image picker using a popover controller, as described in “Presenting and Dismissing the Popover” in UIPopoverController Class Reference. If you attempt to present an image picker modally (full-screen) for choosing among saved pictures and movies, the system raises an exception.

On iPad, if you specify a source type of UIImagePickerControllerSourceTypeCamera, you can present the image picker modally (full-screen) or by using a popover. However, Apple recommends that you present the camera interface only full-screen.

You must use a UIPopoverController to present the image picker for the photo library on the iPad.
