ios - Separate cookie storage for two (UIWebView or WKWebView)

Question

I want to login many accounts of same site in different webView. For example i have Tab Bar Controller that contains three view controllers and each view controllers contain webView. And for example i embed stackoverflow url for webView in every class. How user can login to different accounts at the same time using these three webView? I've tried this but i can just login one user at a time. I have found that i need to create separate cookie for every UIWebView, but mostly answers are in objective-c and not the proper answer i want. For example (First Second Third) Can any one please tell me how i can do it?

class FirstViewController: UIViewController , UIWebViewDelegate{

    @IBOutlet weak var webView: UIWebView!
    @IBOutlet weak var activityIndicator: UIActivityIndicatorView!

    override func viewDidLoad() {
        webView.delegate = self
        let requestURL = NSURL(string: "http://stackoverflow.com")
        let request = NSURLRequest(URL: requestURL!)
        activityIndicator.hidesWhenStopped = true
        activityIndicator.startAnimating()
        webView.loadRequest(request)

    }
       func webViewDidFinishLoad(webView: UIWebView) {
        activityIndicator.stopAnimating()
    }

}

class SecondViewController: UIViewController, UIWebViewDelegate{

    @IBOutlet weak var webView: UIWebView!
    @IBOutlet weak var activityIndicator: UIActivityIndicatorView!

    override func viewDidLoad() {
        webView.delegate = self
        let requestURL = NSURL(string: "http://stackoverflow.com")
        let request = NSURLRequest(URL: requestURL!)
        activityIndicator.hidesWhenStopped = true
        activityIndicator.startAnimating()
        webView.loadRequest(request)

    }
        func webViewDidFinishLoad(webView: UIWebView) {
        activityIndicator.stopAnimating()
    }


}

Thanks

您可以WKWebView通过使用不同的实例来做到这一点WKWebSiteDataStore：

let configuration1 = WKWebViewConfiguration()
configuration1.websiteDataStore = WKWebsiteDataStore.nonPersistent()
self.webView1 = WKWebView(frame: CGRect.zero, configuration: configuration1)
self.view.addSubview(self.webView1)

let configuration2 = WKWebViewConfiguration()
configuration2.websiteDataStore = WKWebsiteDataStore.nonPersistent()
self.webView2 = WKWebView(frame: CGRect.zero, configuration: configuration2)

不幸的是，在应用重启后你会丢失webView数据（例如 cookie、缓存等），因为非持久性WKWebsiteDataStore无法保存到磁盘（你可能会注意到WKWebsiteDataStoreimplements NSCoding，但它不适用于非持久性存储）。
