Have a reloadData for a UITableView animate when changing

Question

I have a UITableView that has two modes. When we switch between the modes I have a different number of sections and cells per section. Ideally, it would do some cool anima

Answer 1

Native UITableView animations in Swift

Insert and delete rows all at once with tableView.performBatchUpdates so they occur simultaneously. Building on the answer from @iKenndac use methods such as:

• tableView.insertSections
• tableView.insertRows
• tableView.deleteSections
• tableView.deleteRows

Ex:

 tableView.performBatchUpdates({
   tableView.insertSections([0], with: .top)
 })

This inserts a section at the zero position with an animation that loads from the top. This will re-run the cellForRowAt method and check for a new cell at that position. You could reload the entire table view this way with specific animations.

Re: the OP question, a conditional flag would have been needed to show the cells for the alternate table view state.
