How do I make the bottom bar with dots of a UIPageViewController translucent?

Question

I\'m in the process of making a tutorial, and I\'m trying to emulate the style of Path\'s tutorial like so:

I wanted to do a similar effect in the app I was working on - I used a UIPageViewController with a separate UIPageControl.

This lets you place the UIPageControl anywhere you'd like in the view, including over the top of the UIPageViewController, and you keep its active page dot up to date via the UIPageViewController delegate method:

- (void)pageViewController:(UIPageViewController *)pageViewController
        didFinishAnimating:(BOOL)finished
   previousViewControllers:(NSArray *)previousViewControllers
       transitionCompleted:(BOOL)completed {
    if (completed) {
        self.pageControl.currentPage = [self.pageViewControllers indexOfObject:pageViewController.viewControllers.firstObject];
    }
}

No need to traverse the subview hierarchy trying to find the internal UIPageViewController page control, nor having to resize the contents of the internal scrollview.

Hope this helps.
