        optionMenu.addAction(callAction)
        
        present(optionMenu, animated: true, completion: nil)
    }

}

开启模拟器，查看功能

点击随便一个餐厅的名称，就会跳出功能选单

点击拨打电话就会显示服务不可用

接着要加上打卡功能，覆蓋以下程式码

        present(optionMenu, animated: true, completion: nil)
        tableView.deselectRow(at: indexPath, animated: true)
    }

}

开启模拟器，点击随便一间餐厅

点击 Check in，就会在那间餐厅后面打勾

现在有一个 Bug，你会发现你点了一间餐厅可是后面的餐厅也会打勾，现在要解决这个问题

覆蓋以下的程式码
