You can use appearance to change the color of UIPageControl as otherwise it is not accessible. Try doing it in your AppDelegate's didFinishLaunchingWithOptions function as given below.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    UIPageControl *pageControl = [UIPageControl appearance];
    pageControl.pageIndicatorTintColor = [UIColor lightGrayColor];
    pageControl.currentPageIndicatorTintColor = [UIColor blackColor];
    pageControl.backgroundColor = [UIColor blueColor];

    return YES;
}

To apply style only to a particular view controller, you can use appearanceWhenContainedIn instead as following:

UIPageControl *pageControl = [UIPageControl appearanceWhenContainedIn:[MyViewController class], nil];

Only UIPageControl objects contained in the MyViewController are going to get this style.

EDIT: The black background around UIPageControl at the bottom of your screen is due to the background color of your UIPageViewController not UIPageControl. You can change this color as following:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor blueColor]; //Set it to whatever you like
}
