首先，在viewDidLoad中初始化相關數據：

  override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        
        //添加刷新
        refreshControl.addTarget(self, action: "refreshData", forControlEvents: UIControlEvents.ValueChanged)
        refreshControl.attributedTitle = NSAttributedString(string: "松手刷新新聞")
        newsTableView.addSubview(refreshControl)
        
    }

完整的代碼如下，因為涉及到 BMOB API 的調用，所以有些代碼可能看不懂，但是並不影響基本功能的使用。
