我对开发很陌生。我正在构建一个 WebView，我希望它具有拉动刷新功能。我该如何快速做到这一点？

我在视图控制器中的代码是

@IBOutlet var webView: UIWebView!

override func viewDidLoad() {
    super.viewDidLoad()

    func webViewDidFinishLoad(webView: UIWebView) {
        UIApplication.sharedApplication().networkActivityIndicatorVisible = false
    }

    func webViewDidStartLoad(webView: UIWebView) {
        UIApplication.sharedApplication().networkActivityIndicatorVisible = true
    }

    let url = NSURL (string: "https://www.foo.com");
    let requestObj = NSURLRequest(URL: url!);
    webView.loadRequest(requestObj);
    NSUserDefaults.standardUserDefaults().registerDefaults(["UserAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/601.5.17 (KHTML, like Gecko) Version/9.1 Safari/601.5.17"])
}


override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()

}
