import UIKit

class ViewController: UIViewController {

override func viewDidLoad() {

super.viewDidLoad()

let progressView = UIProgressView(progressViewStyle: .default)

progressView.center = self.view.center

progressView.progress = 0.5 // 默认 50%

self.view.addSubview(progressView)

progressView.progressTintColor = UIColor.green // 已有进度颜色

progressView.trackTintColor = UIColor.blue  // 剩余进度颜色

progressView.setProgress(0.8, animated: true)

}
