iPhone - how to scroll two UITableViews symmetrically

Question

In my app, I have two tableViews side by side. When the user scrolls on, I would like the second one to scroll at the same time, so it looks almost like one table with two d

Answer 1

UITableView is a subclass of UIScrollView. Swift solution:

extension yourViewController: UIScrollViewDelegate {
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        let otherScrollView = (scrollView == tableViewLeft) ? tableViewRight : tableViewLeft
        otherScrollView?.setContentOffset(scrollView.contentOffset, animated: false)
    }
}

And stop the bounce of both the tables

tableViewLeft.bounces = false
tableViewRight.bounces = false

If you want to make vertical scroll Indicators go, write the below code

tableViewLeft.showsVerticalScrollIndicator = false
tableViewRight.showsVerticalScrollIndicator = false
