在 UITableView 中默认启用重新排序控制，而不处于编辑模式

Question

I am currently working on a solution where I need to have a UITableView by default in reorder mode without having a delete button but could enable the delete button when necessary. I am just curious if this is even achievable in iOS? If so what should be my approach for this?

Answer 1

In my opinion your table view should always be in edit mode.

To make the reorder controls appear you should implement UITableViewDataSource methods

tableView(_ tableView: UITableView, canMoveRowAt indexPath: IndexPath) -> Bool

and

tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath)

If you don't want the delete button to be displayed you can do that by implementing

tableView(_ tableView: UITableView, editingStyleForRowAt indexPath: IndexPath) -> UITableViewCell.EditingStyle

and return.none by default or.delete when you want to have the button displayed.
