Question

我正在尝试在我的应用上添加移动版，桌面版网站功能。但问题是User Agent只在webView加载之前立即更改。在我的应用中，我添加了Mobile的按钮1和Desktop版本网站的第二个按钮。 UIWebView在开始时选择User Agent。任何人都可以告诉我有没有办法在运行时更改User Agent。感谢

 var defaultUserAgent = String()
    @IBOutlet weak var webView: UIWebView!

    @IBOutlet weak var activityIndicator: UIActivityIndicatorView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let url = NSURL(string: "https://www.youtube.com")
        let request = NSURLRequest(URL: url!)
        activityIndicator.hidesWhenStopped = true
        activityIndicator.startAnimating()
        webView.loadRequest(request)
    }

    @IBAction func mobile(sender: AnyObject) {
        NSUserDefaults.standardUserDefaults().registerDefaults(["UserAgent": defaultUserAgent])
        print(defaultUserAgent)

        let url = NSURL(string: "https://www.youtube.com")
        let request = NSURLRequest(URL: url!)
        activityIndicator.hidesWhenStopped = true
        activityIndicator.startAnimating()
        webView.loadRequest(request)

    }

    @IBAction func desktop(sender: AnyObject) {

        NSUserDefaults.standardUserDefaults().registerDefaults(["UserAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.109 Safari/537.36"])

        let url = NSURL(string: "https://www.youtube.com")
        let request = NSURLRequest(URL: url!)
        activityIndicator.hidesWhenStopped = true
        activityIndicator.startAnimating()
        webView.loadRequest(request)

    }

    func webViewDidFinishLoad(webView: UIWebView) {
        activityIndicator.stopAnimating()
        print(webView.stringByEvaluatingJavaScriptFromString("navigator.userAgent"))
        defaultUserAgent = webView.stringByEvaluatingJavaScriptFromString("navigator.userAgent")!
    }

我建议您使用 WkWebView 而不是 UIWebView ，因为它相对更强大

iOS 9的WkWebView具有直接API

$('#text_to speech').click(function(e){

$.ajax({ type: 'GET', data: { text: "text to speech" }, url: '/test' , success: function(response) { console.log('success');  } });
}

用户代理在运行时更改
