Share WKWebView Cookies With UIWebView

Question

I'm trying to share WKWebView Cookies with UIWebView for getting all cookies. I know its very simple to get all cookies from UIWebView as compare WKWebView.

I create two WebView's (WKWebView, UIWebView) in Tabbed Application Template. Below method that i am using for share WKWebView cookies with UIWebView but didn't get success.

func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void) {

     let response = navigationResponse.response as? HTTPURLResponse
     let cookies = HTTPCookie.cookies(withResponseHeaderFields: response?.allHeaderFields as! [String : String], for: (response?.url)!)

     HTTPCookieStorage.shared.cookieAcceptPolicy = HTTPCookie.AcceptPolicy.always

     for cookie in cookies {
     HTTPCookieStorage.shared.setCookie(cookie)
     }

    decisionHandler(WKNavigationResponsePolicy.allow);
 }

Using above code when i Login Into my account from WKWebView, UiWebView didn't Login me already. I also tried to share UIWebView Cookies With WKWebView, and it worked.

Please can anyone tell me how i can share WKWebView Cookies With UIWebView or how i can get all cookies from WKWebView?

Thanks

You need to set the wkwebview cookies by following the steps below

first in the initialization is to execute the script to set up Cookies：

-(void)initWebView
{
    WKWebViewConfiguration *webViewconfiguration = [[WKWebViewConfiguration alloc] init];
    WKUserContentController *wkUController = [[WKUserContentController alloc] init];
    if(URL.host hasSuffix:baseDomain){
    //Here to determine whether the domain name is their own website
        NSString *jScript = [self setCookies];
        WKUserScript *wkUScript = [[WKUserScript alloc] initWithSource:jScript injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
                    [wkUController addUserScript:wkUScript];
}
    webViewconfiguration.userContentController = wkUController;
    WKWebView *webView = [[WKWebView alloc] initWithFrame:CGRectMake(0, 0, width, height) configuration:webViewconfiguration];
}
//The script that executes may be slightly different
+(NSString *)setCookies
{
     NSString *script = [NSString string];

    for (NSHTTPCookie *httpCookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies])
    {
       NSString *cookie = [NSString stringWithFormat:@"%@=%@;domain=%@;path=%@",httpCookie.name,httpCookie.value,httpCookie.domain,httpCookie.path?:@"/"];
       script = [script stringByAppendingString:[NSString stringWithFormat:@"document.cookie='%@';",cookie]];

    }
    return script;
}

And then manually add cookies to the header of the HTTP when creating the NSURLRequest object:

- (void)loadRequest:(NSURLRequest *)request
{
    //Here to determine whether the domain name is their own website
    if ([request.URL.host hasSuffix:baseDomain]){
        NSMutableURLRequest *mutableRequest = [[NSMutableURLRequest alloc] initWithURL:request.URL];
        NSString *cookies = @""; //setting Cookies
        [mutableRequest addValue:cookies forHTTPHeaderField:@"Cookie"];
}
    // do request  
}
