TrailingSwipeAction：如何在滑动时停用自动删除？

Question

我将我的 tablerowactions 更新为 swift 4 等效于能够设置图标而不是文本作为用户在 table 上向左滑动时显示的按钮元素。我的问题是，如果用户从右向左滑动而不是仅显示所有可用操作，则第一个定义的操作（在我的例子中是删除操作）会自动触发。我想停用此行为。我的代码目前看起来像这样：

 override func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let deleteAction = UIContextualAction(style: .normal, title:  "", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
        // implemantion of delete-button here 
        // ...

        success(true)
    })


    deleteAction.image = #imageLiteral(resourceName: "deleteIcon")
    deleteAction.backgroundColor = .red
    return UISwipeActionsConfiguration(actions: [deleteAction])
}

UISwipeActionsConfiguration 有一个属性允许您关闭此行为，称为 performsFirstActionWithFullSwipe。 (Documentation)

所以代替：

return UISwipeActionsConfiguration(actions: [deleteAction])

做这样的事情：

let configuration = UISwipeActionsConfiguration(actions: [deleteAction])
configuration.performsFirstActionWithFullSwipe = false
return configuration
