学习笔记：UIProgressView

代码如下：

import UIKitclass ViewController: UIViewController {    @IBOutlet weak var progress: UIProgressView!    @IBOutlet weak var label: UILabel!    @IBOutlet weak var activity: UIActivityIndicatorView!    @IBOutlet weak var beginBtn: UIButton!    var timer:NSTimer!    var remainTime = 0    override func viewDidLoad() {        super.viewDidLoad()        // Do any additional setup after loading the view, typically from a nib.        label.text = ""    }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }    @IBAction func BeginClicked(sender: UIButton) {        //禁用按钮        beginBtn.enabled = false        //开始滚动轮        activity.startAnimating()        //设置        timer = NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector:"timerAction", userInfo: nil, repeats: true)        timer.fire()    }    func timerAction() {        //计时器结束时状态        if (remainTime == 100){            timer.invalidate()            activity.stopAnimating()            beginBtn.enabled = true            label.text = ""            progress.progress = 0.0            remainTime = 0        //计时器进行时状态        } else {            remainTime = remainTime + 10            label.text = "完成\(remainTime)%"            let progressValue = Float(remainTime)/100            //设置进度条的进度            progress.setProgress(progressValue, animated:true)        }    }}
