【问题描述】：

我在 tableview 中添加了两个动作领先的滑动动作，但只有背景显示，标题不可见。

func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? 
    let card = savedCards[indexPath.row]

//    if !card.isDefault
        let makeDefault = UIContextualAction(style: .normal, title: "Make as Default")  (action, sourceView, completionHandler) in
            print("index path of default: \(indexPath)")

        

        let closeAction = UIContextualAction(style: .normal, title:  "Mark as Read", handler:  (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
            print("CloseAction ...")
            success(true)
        )
        closeAction.backgroundColor = .blue

        let swipeActionConfig = UISwipeActionsConfiguration(actions: [makeDefault,closeAction])
        swipeActionConfig.performsFirstActionWithFullSwipe = true
        return swipeActionConfig
  //  

    return nil

【参考方案1】：

func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? 

            let makeDefault = UIContextualAction(style: .normal, title: "Make as Default")  (action, sourceView, completionHandler) in
                print("index path of default: \(indexPath)")

            

            let closeAction = UIContextualAction(style: .normal, title:  "Mark as Read", handler:  (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
                print("CloseAction ...")
                success(true)
            )
            closeAction.backgroundColor = .blue

            let swipeActionConfig = UISwipeActionsConfiguration(actions: [makeDefault,closeAction])
            swipeActionConfig.performsFirstActionWithFullSwipe = true
            return swipeActionConfig
