Remove page indicator from UIPageViewController

I am using a pageview controller in an iOs app. How do I remove points from this controller?

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.dontShowChecked = NO;
    self.imagesArray = @[  ..];

    self.textsArray = @[ ........
                        ];


    // Create page view controller
    self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"WTPageController"];
    self.pageViewController.dataSource = self;

    WTDetailViewController *startingViewController = [self viewControllerAtIndex:0];
    NSArray *viewControllers = @[startingViewController];
    [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

    // Change the size of page view controller
    CGFloat delta = [[PSDeviceInfo sharedInstance] is_iPhone] ? 50. : 50;

    self.pageViewController.view.frame = CGRectMake(0, 40., self.view.frame.size.width, self.view.frame.size.height - delta);
    [self.view addSubview:_pageViewController.view];
    [self.pageViewController didMoveToParentViewController:self];
}

      

Dots seem to be automatically added and interfere with other UI elements in this area. How do I completely remove them?

Points are added as soon as your data source UIPageViewController

implements the following methods:

presentationCountForPageViewController:
presentationIndexForPageViewController:

      



Avoid using those that get rid of the UIPageControl dots.

If the pages are zoomed in or out dynamically .

So, I used below method which will manually hide the component itself.

func togglePageControl(pageCount: Int, threshold: Int = 1) {

    var hidden = true

    if pageCount > threshold {

        hidden = false

    }

    for subView in self.view.subviews {
        if subView is UIScrollView {
            subView.frame = self.view.bounds
        } else if subView is UIPageControl {
            subView.isHidden = hidden
        }
    }
}

      



And it needs to be called from

 public func presentationCount(for pageViewController: UIPageViewController) -> Int {

     togglePageControl(pageCount: pages.count)

     // or togglePageControl(pageCount: pages.count, threshold: 5)

     return pages.count
 }

The page control is displayed only if the data source implements these methods:

presentationCount:
presentationIndex:

      

0
