iOS tableview how can I check if it is scrolling up or down

Question

I am learning how to work with TableViews and I am wondering how can I figure out if the tableView is scrolling up or down ? I been trying various things such as this but it

Answer 1

first we should make two property for last Offset and Current Offset

 var lastOffset = CGFloat()
 var currentOffset = CGFloat()

then in the Scrollview VC call the scrollViewWillBeginDragging for get current offset

 override func scrollViewWillBeginDragging(_ scrollView: UIScrollView) {

        self.lastOffset = scrollView.contentOffset.y

    }

and scrollViewWillBeginDecelerating for get last offset

    override func scrollViewWillBeginDecelerating(_ scrollView: UIScrollView) {

        self.lastOffset = scrollView.contentOffset.y
        viewStatus(scrollView: scrollView)

    }

then with this two variable you can know your scrollview W here it goes‍‍‍‍

‍‍‍let isScrollUp = scrollView.contentOffset.y > self.lastOffset
let isScrollDown  = scrollView.contentOffset.y < self.lastOffset
