Use the imageOrientation property of UIImage instances. It is going to return you one of these constants.

Example:

UIImage *image = // loaded from library

if (image.imageOrientation == UIImageOrientationUp) {
    NSLog(@"portrait");
} else if (image.imageOrientation == UIImageOrientationLeft || image.imageOrientation == UIImageOrientationRight) {
    NSLog(@"landscape");
}
