Swift scrollToRow然后突出显示该行

Question

What I would like to do is scrollToRow, then animate the background of that row so it's background changes visibly, so the user can see that exact row.

I have a table with ~100 rows, and when scrollToRow is triggered, it scrolls to the right row, but it gets lost in the other rows. I just want the user to have the ability to spot that row more easily...

You can use, any of following solutions, all them works fine:

scrollToRow(at:at:animated:)

Scrolls through the table view until a row identified by index path is at a particular location on the screen.

func scrollToRow(at indexPath: IndexPath, at scrollPosition: UITableViewScrollPosition, animated: Bool)

scrollToNearestSelectedRow(at:animated:)

Scrolls the table view so that the selected row nearest to a specified position in the table view is at that position.

func scrollToNearestSelectedRow(at scrollPosition: UITableViewScrollPosition, animated: Bool)

scrollRectToVisible(_:animated:)

Scrolls a specific area of the content so that it is visible in the receiver. Use scrollview of tableview to achieve this result

func scrollRectToVisible(_ rect: CGRect, animated: Bool)

selectRow(at:animated:scrollPosition:)

Selects a row in the table view identified by index path, optionally scrolling the row to a location in the table view.

func selectRow(at indexPath: IndexPath?, animated: Bool, scrollPosition: UITableViewScrollPosition)
