How to Manage Cookies with Uiwebview in Swift

How to manage cookies with UIWebView in Swift

Try this code:

SEE COOKIES STORED

    if let cookies = NSHTTPCookieStorage.sharedHTTPCookieStorage().cookies {
        for cookie in cookies {
            NSLog("\(cookie)")
        }
    }

DELETE STORED COOKIES

    var storage : NSHTTPCookieStorage = NSHTTPCookieStorage.sharedHTTPCookieStorage()
    for cookie in storage.cookies  as! [NSHTTPCookie]{
        storage.deleteCookie(cookie)
    }

swift 2.0

let storage = NSHTTPCookieStorage.sharedHTTPCookieStorage()
for cookie in storage.cookies! {
 storage.deleteCookie(cookie)
}

Swift 3.0

if let cookies = HTTPCookieStorage.shared.cookies {
    for cookie in cookies {
        NSLog("\(cookie)")
    }
}

let storage = HTTPCookieStorage.shared
for cookie in storage.cookies! {
    storage.deleteCookie(cookie)
}

iOS How to add cookie to each UIWebView request?

Thanks for your help. Problem was solved by creating a cookie with specific domain:

final class FieldServiceViewController: UIViewController, DLHasHomeTitleView {

    private let fieldServiceEndPoint = Bundle.main.object(forInfoDictionaryKey: "FIELD_SERVICE_ENDPOINT") as! String

    private var webView = UIWebView()
    private var sessionID = String()

    override func viewDidLoad() {
        super.viewDidLoad()

        configureUI()

        _ = JSONAPI.getSessionID().subscribe(onNext: { [weak self] sessionID in
            guard let `self` = self else { return }

            self.sessionID = sessionID

            let urlString = "https://\(self.fieldServiceEndPoint)"
            let url = URL(string: urlString)
            let request = URLRequest(url: url!)

            let cookie = HTTPCookie(properties: [
                .name: "JSESSIONID",
                .value: sessionID,
                .path: "/",
                .domain: self.fieldServiceEndPoint])
            HTTPCookieStorage.shared.setCookie(cookie!)

            self.webView.loadRequest(request)
        })
    }

Getting all cookies from WKWebView

Finally, httpCookieStore for WKWebsiteDataStore landed in iOS 11.

How to delete all cookies of UIWebView?

According to this question, you can go through each cookie in the "Cookie Jar" and delete them, like so:

NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (NSHTTPCookie *cookie in [storage cookies]) {
   [storage deleteCookie:cookie];
}
[[NSUserDefaults standardUserDefaults] synchronize];

Can I set the cookies to be used by a WKWebView?

Edit for iOS 11+ only

Use WKHTTPCookieStore:

let cookie = HTTPCookie(properties: [
    .domain: "example.com",
    .path: "/",
    .name: "MyCookieName",
    .value: "MyCookieValue",
    .secure: "TRUE",
    .expires: NSDate(timeIntervalSinceNow: 31556926)
])! 

webView.configuration.websiteDataStore.httpCookieStore.setCookie(cookie)

Since you are pulling them over from HTTPCookeStorage, you can do this:

let cookies = HTTPCookieStorage.shared.cookies ?? []
for cookie in cookies {
    webView.configuration.websiteDataStore.httpCookieStore.setCookie(cookie)
}

Old answer for iOS 10 and below

If you require your cookies to be set on the initial load request, you can set them on NSMutableURLRequest. Because cookies are just a specially formatted request header this can be achieved like so:

WKWebView * webView = /*set up your webView*/
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://example.com/index.html"]];
[request addValue:@"TeskCookieKey1=TeskCookieValue1;TeskCookieKey2=TeskCookieValue2;" forHTTPHeaderField:@"Cookie"];
// use stringWithFormat: in the above line to inject your values programmatically
[webView loadRequest:request];

If you require subsequent AJAX requests on the page to have their cookies set, this can be achieved by simply using WKUserScript to set the values programmatically via javascript at document start like so:

WKUserContentController* userContentController = WKUserContentController.new;
WKUserScript * cookieScript = [[WKUserScript alloc] 
    initWithSource: @"document.cookie = 'TeskCookieKey1=TeskCookieValue1';document.cookie = 'TeskCookieKey2=TeskCookieValue2';"
    injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
// again, use stringWithFormat: in the above line to inject your values programmatically
[userContentController addUserScript:cookieScript];
WKWebViewConfiguration* webViewConfig = WKWebViewConfiguration.new;
webViewConfig.userContentController = userContentController;
WKWebView * webView = [[WKWebView alloc] initWithFrame:CGRectMake(/*set your values*/) configuration:webViewConfig];

Combining these two techniques should give you enough tools to transfer cookie values from Native App Land to Web View Land. You can find more info on the cookie javascript API on Mozilla's page if you require some more advanced cookies.

Yeah, it sucks that Apple is not supporting many of the niceties of UIWebView. Not sure if they will ever support them, but hopefully they will get on this soon. Hope this helps!

Disable Cookies UIWebView Swift iOS

Try to This

let storage = NSHTTPCookieStorage.sharedHTTPCookieStorage()
for cookie in storage.cookies! {
 storage.deleteCookie(cookie)
}
NSUserDefaults.standardUserDefaults().synchronize()

Clear webView cookies (Swift)

I made it by

        let cookieJar = NSHTTPCookieStorage.sharedHTTPCookieStorage()

        for cookie in cookieJar.cookies! {
           // print(cookie.name+"="+cookie.value)
            cookieJar.deleteCookie(cookie)
        }

Swift 4

func removeCookies(){
    let cookieJar = HTTPCookieStorage.shared

    for cookie in cookieJar.cookies! {
        cookieJar.deleteCookie(cookie)
    }
}
