Swift开发之使用UIRefreshControl实现下拉刷新数据及uirefreshcontrol使用

import UIKit
class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
 //新闻列表
 @IBOutlet weak var newsTableView: UITableView!
 //新闻数组集合
 var dataArray:[HanggeArticle] = [HanggeArticle]()
 //拉刷新控制器
 var refreshControl = UIRefreshControl()
 override func viewDidLoad() {
  super.viewDidLoad()
  self.automaticallyAdjustsScrollViewInsets = false
  //添加刷新
  refreshControl.addTarget(self, action: "refreshData",
   forControlEvents: UIControlEvents.ValueChanged)
  refreshControl.attributedTitle = NSAttributedString(string: "下拉刷新数据")
  newsTableView.addSubview(refreshControl)
  refreshData()
 }
 // 刷新数据
 func refreshData() {
  //移除老数据
  self.dataArray.removeAll()
  //随机添加条新数据（时间是当前时间）
  for _ in ..< {
   let atricle = HanggeArticle(title: "新闻标题\(Int(arcrandom()%))",
    createDate: NSDate())
   self.dataArray.append(atricle)
  }
  self.newsTableView.reloadData()
  self.refreshControl.endRefreshing()
 }
 // 返回记录数
 func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
  return dataArray.count;
 }
 // 返回单元格内容
 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath)
  -> UITableViewCell {
  let cell = UITableViewCell(style: UITableViewCellStyle.Subtitle,
   reuseIdentifier: "myCell")
  //设置单元格标题
  let atricle: HanggeArticle = dataArray[indexPath.row] as HanggeArticle
  cell.textLabel?.text = atricle.title
  //设置单元格副标题
  let dateFormatter = NSDateFormatter()
  dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
  let str = dateFormatter.stringFromDate(atricle.createDate)
  cell.detailTextLabel?.text = str
  return cell;
 }
 override func didReceiveMemoryWarning() {
  super.didReceiveMemoryWarning()
 }
}
//新闻结构体
struct HanggeArticle {
 var title:String
 var createDate:NSDate
}
