这是我的代码:

@IBOutlet weak var webView: WKWebView!
@IBOutlet weak var progressView: UIProgressView!

override func viewDidLoad() {
    super.viewDidLoad()

    webView.uiDelegate = self
    webView.navigationDelegate = self

    webView.addObserver(self, forKeyPath: "estimatedProgress", options: .new, context: nil)        
}

override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
    if (keyPath == "estimatedProgress") {
        progressView.setProgress(Float(webView.estimatedProgress), animated: true)
        print(webView.estimatedProgress)
    }
}

但是,估计进度只显示两个浮点数(0.1和1.0)而且我觉得它不起作用.我使用了Alamofire的进度,它改变了几毫秒,使我的UI更好,但这段代码不能正常工作......

有谁可以帮助我进行webView的进展？
