How to get cookies from WKWebView?

Question

How to get all cookies from an instance of WKWebView?

Here is what I have tried so far:

• I tried using - [WKWebView evaluateJavaScript:completionHandler:] to evaluate document.cookie - unfortunately, the result does not contain cookies marked as HttpOnly .

• According to Introducing the Modern WebKit API (WWDC 2014 Session 206) , you can get a response object from an instance of WKNavigation . However, according to the class reference , WKNavigation does not contain a public method / property.

Since this question has not received an answer in a year, I am sending my imperfect, but working solution:

You can have access to the NSHTTPURLResponse object in the method - webView:decidePolicyForNavigationResponse:decisionHandler: defined in WKNavigationDelegate . You can subsequently extract the cookies manually from the HTTP header:

 - (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler { NSHTTPURLResponse* response = navigationResponse.response; NSArray *cookies = [NSHTTPCookie cookiesWithResponseHeaderFields:[response allHeaderFields] forURL:[NSURL URLWithString:@""]]; for (NSHTTPCookie *cookie in cookies) { // Do something with the cookie } decisionHandler(WKNavigationResponsePolicyAllow); } 

Please post your decision if you have the best.
