If you have your UITableViews snap to their cells, you’ll end up with a more refined user experience. This solution I have works with cells that are consistent in their height (static). You could always work with dynamic heights if you wanted to.
func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
if scrollView == suggestionsTableView {
let cellHeight = CGFloat(60.0)
let y = targetContentOffset.pointee.y + scrollView.contentInset.top + (cellHeight / 2)
let cellIndex = floor(y / cellHeight)
targetContentOffset.pointee.y = cellIndex * cellHeight - scrollView.contentInset.top
}
}
As you can see cellHeight is a set float value, it’s there where you would want to determine the dynamic height. This little bit of code makes a UITableView a lot more refined as it doesn’t clip cell contents when a user lifts their finger from a drag.
