UIPageControl not appearing when Vertical is selected

Question

I can get the UIPageControl to work when the PageViewController Navigation style is set to Horizontal, however when I choose Vertical the UIPageControl does not appear horizontal or vertical.

I am setting the appearance of my UIPageControl in the AppDelegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.

    UIPageControl *pageControl = [UIPageControl appearance];
    pageControl.pageIndicatorTintColor = [UIColor lightGrayColor];
    pageControl.currentPageIndicatorTintColor = [UIColor blackColor];
    pageControl.backgroundColor = [UIColor whiteColor];

    return YES;
}

Is there a way to make it appear in a vertical position? The code above works when the Horizontal option is selected for navigation but not when the Vertical is selected.

If I understand correctly, what you want to do is to use UIPageViewController with vertical orientation and also display the UIPageControl vertically. I tried to do that, but it seems that the UIPageControl related to the UIPageViewController is not accessible directly.

However, I found a very satisfactory workaround to your problem. Use UIScrollView with pagingEnabled and manage the UIPageControl in the scrollView's delegate methods. To display the UIPageControl vertically, you can use

pageControl.transform = CGAffineTransformMakeRotation(M_PI / 2);

I made a sample application demonstrating this workaround. Here is the download link. Consider accepting the question if it helped you solve the problem, thanks.
