UIProgressView

     override func viewDidLoad() {
         super.viewDidLoad()

         titleLabel.text = titleString

         // Do any additional setup after loading the view.

         //创建进度控制器
         var progressView:UIProgressView = UIProgressView(frame: CGRectMake(, , , ))

         //添加到视图上
         self.view.addSubview(progressView)

         //设置进度
         progressView.progress = 0.5
         //或
         progressView.setProgress(0.5, animated: true)

         //设置风格
         progressView.progressViewStyle = UIProgressViewStyle.Default

         //
         progressView.tintColor = UIColor.greenColor()

         //--------使用颜色来美化进度控制器
         //当前进度颜色
         progressView.progressTintColor = UIColor.redColor()

         //背景颜色
         progressView.trackTintColor = UIColor.blueColor()

         //--------使用图片来美化进度控制器
         //设置进度的图片
         progressView.progressImage = UIImage(named: "leftTrack.png")
