Adding dots to bottom of UIPageViewController screen

When you use UIPageViewController the dots should be visible by default. I guess you have a white background and the dots are also white, so you just don't see them.

Try to change dots color:

Swift 4/5:

var appearance = UIPageControl.appearance(whenContainedInInstancesOf: [UIPageViewController.self])appearance.pageIndicatorTintColor = UIColor.redappearance.currentPageIndicatorTintColor = UIColor.red

Swift 3:

var appearance = UIPageControl.appearanceWhenContainedIn(UIPageViewController.self, nil)appearance.pageIndicatorTintColor = UIColor.redappearance.currentPageIndicatorTintColor = UIColor.red

If it doesn't help, make sure that you are using UIPageViewControllerTransitionStyleScroll transition style.

Also, make sure to implement this methods from the UIPageViewControllerDataSource: presentationCount(for:) and presentationIndex(for:).

For Swift 3.0, you need:

private func setupPageControl() {    let appearance = UIPageControl.appearance()    appearance.pageIndicatorTintColor = UIColor.gray    appearance.currentPageIndicatorTintColor = UIColor.white    appearance.backgroundColor = UIColor.darkGray}func presentationCount(for pageViewController: UIPageViewController) -> Int {    setupPageControl()    return self.images.count}func presentationIndex(for pageViewController: UIPageViewController) -> Int {    return 0}

If anyone is searching for this kind of question still, I found a good tutorial about adding the page dots to your UIPageViewController. It worked for me, at least.

This is the relevant part for this question:

Make sure you have the appropriate delegate and datasource

import UIKitclass PageViewController: UIPageViewController, UIPageViewControllerDelegate, UIPageViewControllerDataSource

To add the page dot indications add a pageControl as follows:

create an instance of UIPageControl.

var pageControl = UIPageControl()

Now add the following function. This will position the page control at the bottom of the screen. The current page indication will be black, and the rest of the indicators will be white. You can change these to suit the design of your app.

func configurePageControl() {    pageControl = UIPageControl(frame: CGRect(x: 0,y: UIScreen.main.bounds.maxY - 50,width: UIScreen.main.bounds.width,height: 50))    self.pageControl.numberOfPages = orderedViewControllers.count    self.pageControl.currentPage = 0    self.pageControl.alpha = 0.5    self.pageControl.tintColor = UIColor.black    self.pageControl.pageIndicatorTintColor = UIColor.white    self.pageControl.currentPageIndicatorTintColor = UIColor.black    self.view.addSubview(pageControl)}

Now in viewDidLoad() add these two lines:

self.delegate = selfconfigurePageControl()

And add the following function, this will make sure the page control indicator changes to the correct page as you scroll through.

// MARK: Delegate functionsfunc pageViewController(_ pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) {    let pageContentViewController = pageViewController.viewControllers![0]    self.pageControl.currentPage = orderedViewControllers.index(of: pageContentViewController)!}
