How to know that tableView started scrolling

Question

I have a doubt: is there any way to intercept a tableView scrolling to add it an action? For example my prototype cell background is red, touching up inside a cell its background color begin blue and scrolling the tableView background color return red. Is it possible to do this?!

Thanks in advance.

Solution

UITableView inherits from UIScrollView and UITableViewDelegate extends UIScrollViewDelegate.

Particularly you may be interested in scrollViewDidScroll method. So, in your UITableViewDelegate implementation, add the following method:

func scrollViewDidScroll(_ scrollView: UIScrollView) {
    NSLog("Table view scroll detected at offset: %f", scrollView.contentOffset.y)
}
