Answer 1

You should be able to do this by simply adding this code to your app delegate.

Swift code:

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> Int {
    if UIDevice.currentDevice().userInterfaceIdiom == .Phone {
        return Int(UIInterfaceOrientationMask.Portrait.rawValue)
    } else {
        return Int(UIInterfaceOrientationMask.LandscapeLeft.rawValue | UIInterfaceOrientationMask.LandscapeRight.rawValue)
    }
}

Answer 2

So here is what I did

For iPhone

and for iPad

And for iPad controllers I added below code, this is not necessary for ios6 applications

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight ||
            interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
