Add the following code in the UIPageViewController.

- (void)viewDidLoad {
    [super viewDidLoad];
    [[UIPageControl appearance] setPageIndicatorTintColor: [UIColor grayColor]];
    [[UIPageControl appearance] setCurrentPageIndicatorTintColor: [UIColor whiteColor]];
    [[UIPageControl appearance] setBackgroundColor: [UIColor darkGrayColor]];
}

Answer 2

Here is the Swift 2+ version of Yas-T's Answer

//In AppDelegate
let pageControl = UIPageControl.appearance()
pageControl.pageIndicatorTintColor = UIColor.lightGrayColor()
pageControl.currentPageIndicatorTintColor = UIColor.blackColor()
pageControl.backgroundColor = UIColor.blueColor()

//Or in your ViewController (Only available on IOS 9.0)
if #available(iOS 9.0, *) {
   let pageControl = UIPageControl.appearanceWhenContainedInInstancesOfClasses([ViewController.self])
   pageControl.pageIndicatorTintColor = UIColor.lightGrayColor()
   pageControl.currentPageIndicatorTintColor = UIColor.darkGrayColor()
}

Answer 3

Well, I found a working solution. Inside your UIPageViewController, just add this code:

-(void)viewDidLayoutSubviews
{
   [super viewDidLayoutSubviews];

   for (UIView *view in self.view.subviews)
   {
       if ([view isKindOfClass:UIScrollView.class])
       {
           CGRect frame      = view.frame;

           frame.size.height = view.superview.frame.size.height;

           view.frame        = frame;
       }

       if ([view isKindOfClass:UIPageControl.class])
       {
           CGFloat newHeight    = 22;

           CGRect frame         = view.frame;

           frame.origin.y      += frame.size.height - newHeight;
           frame.size.height    = newHeight;

           view.frame           = frame;
           view.backgroundColor = UIColor.darkGrayColor;
           view.alpha           = 0.3;
       }
   }

}
