What's the best way of handling a UIPageControl that has so many dots they don't all fit on the screen

Question

I have a UIPageControl in my application that looks perfectly fine with around 10 pages (dots), it\'s possible however for the user to add many different views, and so the numbe

Answer 1

My solution is setting the maximum number of dots and showing the dot before the last one until the user reaches the end. If the current page number is bigger than maximum dot count we show the one before the last one until the user reaches the end.

var maxDotCount = 8   //Global constant.

func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
        let pageWidth = collectionView.frame.size.width
        let currentPage = collectionView.contentOffset.x / pageWidth
        let pageControlsNumberOfPages = pageControl.numberOfPages - 1
        let dataSourceCount = CGFloat(dataSourceArr.count - 1)
        let maxDotCountReduced = CGFloat(maxDotCount - 1)

        if (dataSourceCount > maxDotCountReduced) {
            if (currentPage >= maxDotCountReduced) {
                if (currentPage == dataSourceCount) {
                    pageControl.currentPage = pageControlsNumberOfPages
                } else {
                    pageControl.currentPage = pageControlsNumberOfPages - 1
                }
                return
            }
        }
        pageControl.currentPage = Int(currentPage)
    }
