iOS 7: Restrict device current orientation when modal view controller is presented

I have a UIViewController which contains a UICollectionView. On tapping any of the UICollectionViewCell I present a modal view controller.

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
PopViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"DetailsView"];
vc.view.backgroundColor = [UIColor clearColor];
vc.transitioningDelegate = self;
vc.modalPresentationStyle = UIModalPresentationCustom;
[self presentViewController:vc animated:YES completion:nil];

The PopViewController shows up correctly. Now I want to restrict the device orientation when PopViewController is being presented. That is if PopViewController is presented in portrait mode then it should not change to landscape even if I switch to landscape mode (using Rotate Left or Right in simulator) until I dismiss the PopViewController.

I have used following code in PopViewController:

-(BOOL)shouldAutorotate {
    return NO;
}

What else (or instead) is needed to lock the pop up view to the current orientation?

in your modal controller try to add this, also (iOS > 6)

-(NSUInteger)supportedInterfaceOrientations
{
         return UIInterfaceOrientationMaskPortrait;
}

to support iOS 5 or below you must additional add:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{

   return (toInterfaceOrientation == UIInterfaceOrientationPortrait);

}
