UITableViewCell minimize and maximize animation

Question

I have a UITableView and when a cell is selected it reloads a different type of cell (to simulate the maximize and minimize effect). The problem is I cannot figure how to animate that properly since reloadData() method is called. I achieved some kind of animation using

UIView.transition(with: tableView,
                          duration: 0.35,
                          options: .transitionCrossDissolve,
                          animations: { self.tableView.reloadData() 
})

but it's not really how I want it to look at the end. Did anyone do the same thing and has a better solution?

Answer 1

If you want an animated change don't use reloadData.

Use reloadRowsAtIndexPaths:withRowAnimation: and specify the indexPaths that have changed.
