No, you can't do this automagically. Querying the device rotation and selecting an image based on that is perfectly fine.

You really only need Portrait or Landscape in this situation though, assuming you are rotating your view properly.

As already stated by Joshua you cannot, as far as I am aware.

In case this might help someone else, if you are using asset catelogs the following code should provide the correct launch image for the current interface orientation.

NSString *suffix = nil;

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
    suffix = [[UIScreen mainScreen] bounds].size.height >= 568.0f ? @"-568h@2x" : @"@2x";
}
else {
    UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
    suffix = UIInterfaceOrientationIsPortrait(orientation) ? @"-Portrait" : @"-Landscape";
    suffix = [UIScreen mainScreen].scale == 2.0 ? [suffix stringByAppendingString:@"@2x~ipad"] : [suffix stringByAppendingString:@"~ipad"];
}

NSString *launchImageName = [NSString stringWithFormat:@"LaunchImage-700%@.png",suffix];
