Horizontal padding between UIPageViewController child view controllers

I am using UIPageViewController to display images that are embedded in child view controllers. ``` NSDictionary *options = [NSDictionary dictionaryWithObject: [NSNumber numberWithInteger:UIPageViewControllerSpineLocationMin] forKey: UIPageViewControllerOptionSpineLocationKey]; self.pageViewController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options: options]; self.pageViewController.dataSource = self; self.pageViewController.view.frame = self.view.bounds; ImageViewController *initialViewController = [self viewControllerAtIndex:0]; initialViewController.index = 0; NSArray *viewControllers = [NSArray arrayWithObject:initialViewController]; [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil]; [self addChildViewController:self.pageViewController]; [self.view addSubview:self.pageViewController.view]; [self.pageViewController didMoveToParentViewController:self]; ``` Everything works great but I hate that the child view controllers are right next to one another. I was wondering if there was a way to add padding between the child view controllers so that way they're not right next to one another. Something that would look more like this:
