Connect carousel to pageControl

[Bertges]

Hi, I'm facing the same problem specified in this issue:

https://github.com/ink-spot/UPCarouselFlowLayout/issues/23

In his case, he's using another framework, but I want to keep using UPCarouselFlowLayout.

There is an easy way to get the current page?

Solved my problem by getting the indexPath of the center colectionView cell.

func scrollViewDidScroll(_ scrollView: UIScrollView) {
        let center = CGPoint(x: scrollView.contentOffset.x + (scrollView.frame.width / 2), y: (scrollView.frame.height / 2))
        if let ip = self.collectionView!.indexPathForItem(at: center) {
            self.pageControl.currentPage = ip.row
        }
    }
