That doesn't match what I need. Ok, here is what I have : My data is the @items variable which is an array of objects. My tableView is @tableView. The action is a reaction to a click on a remove button after a selection in the table.
What I want to do is something like this : def removeItems(sender) indexes = @tableView.selectedRowsIndexes @items.delete_at(indexes) @tableView.reloadData end But I can't get a way to make it work.
