Thank you for your answer. I understood that WKWebview does not recognize the cookie store of the process. It is difficult to handle WKWebview (cookie store) on iOS 9. I am considering support for iOS 11, WKWebview and WKHTTP cookie store will work properly on iOS 10 or earlier devices? Please let me know if there is a problem with iOS version. Thank you

Supported cookie sync with

WKWebView

• You can set a cookie in the headers of the request you pass to

  -[WKWebView loadRequest:]

  .

• You can get and set cookies from within the web view by running JavaScript code (using

  -evaluateJavaScript:completionHandler:

  ) that accesses the JavaScript

  document.cookie

  value.

However, these approaches might not working depending on the specifics of your cookies.

Thank you so much. I tried the technique that you taught, but unfortunately the synchronization of cookies did not work well. I would like to think about other methods.

I to had the same issues with this WKHTTPCookieStorage, i created a wrapper method that would add an array of cookie async and on completion it would load the URLRequest in the WKWebView, however when it gets into decidePolicyFor navigationAction method the wkwebview cookies are not the ones i set before in WKHTTPCookieStorage, i believe WKProcessPool is the one responsible for the cookies to be in sync, and it seems that settings cookies in a webview that is created and has a configuration, does not mean that they will be in the wkwebview when the webpage starts loading. i actually created a post with what seems to be a similar issue to yours.

It would be good to know if this is by design, or is it potentially a bug. If it is by design why does this happen, and what workarounds can be used.

My recommendation here is that you open a DTS tech support incident for this. I’m happy to look into it, but I just don’t have enough time for it in the context of DevForums.

I have met another question with wkwebview, I press home button to deactive app using webview, when I reactive the app and press go back button to navigate wkwebview, the wkwebview reload h5 url automactically, this only occurs when I deactive the app and reopen it, how can I prevent it to reload h5, thx.

As this question is unrelated to cookies, you should start a new thread for it.

Hey guy, how can you fix the bug.

How to synchronize cookie in WKWebview of earlier than ios 11

Could you show me the code? Thanks !

My post from 15 Jan explains the options you have prior to iOS 11. I recommend that you try these out and come back to us if you have specific questions.

The WKHTTPCookieStore not working on iOS 11.3 I tried below options but nothing worked for me

let auc = HTTPCookie.init(properties: [HTTPCookiePropertyKey.name: "OAuth.AccessToken", HTTPCookiePropertyKey.value: authToken, HTTPCookiePropertyKey.domain: ".myDomain.com", HTTPCookiePropertyKey.path: "/", HTTPCookiePropertyKey.secure: "TRUE"])

// Here I tried two options, setting the cookie in configuration before the webview
// is created and also after the webview is created.
if let ac = auc {
    if #available(iOS 11.0, *) {
        webView.configuration.websiteDataStore.httpCookieStore.setCookie(ac) {
            DispatchQueue.main.async {
                self.webView.load(checkoutRequest)
            }
        }
    } else {
        // fallback
    }
}
