How to delete WKWebview cookies

Question

For now I am doing like this

    NSHTTPCookie *cookie;
    NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    for (cookie in [         


        

Answer 1

None of these options worked for me but I found one that did:

let config = WKWebViewConfiguration()
if #available(iOS 9.0, *) {
    config.websiteDataStore = WKWebsiteDataStore.nonPersistentDataStore()
} else {
     // I have no idea what to do for iOS 8 yet but this works in 9.
}

let webView = WKWebView(frame: .zero, configuration: config)

Answer 2

Esqarrouth's answer is only partially right.
The correct swift version is:

var libraryPath : String = NSFileManager().URLsForDirectory(.LibraryDirectory, inDomains: .UserDomainMask).first!.path!
libraryPath += "/Cookies"
do {
    try NSFileManager.defaultManager().removeItemAtPath(libraryPath)
} catch {
    print("error")
}
NSURLCache.sharedURLCache().removeAllCachedResponses()

Answer 3

Swift version:

var libraryPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.LibraryDirectory, NSSearchPathDomainMask.UserDomainMask, false).first!
libraryPath += "/Cookies"

do {
  let result = try NSFileManager.defaultManager().removeItemAtPath(libraryPath)
  print(result)
} catch {
  print("error")
}
NSURLCache.sharedURLCache().removeAllCachedResponses()

Apple released new APIs for iOS 9, so now we can remove domain specific cookies stored for WKWebView with below code, but this will only work on devices with iOS version 9 or later:

WKWebsiteDataStore *dateStore = [WKWebsiteDataStore defaultDataStore];
[dateStore
   fetchDataRecordsOfTypes:[WKWebsiteDataStore allWebsiteDataTypes]
   completionHandler:^(NSArray<WKWebsiteDataRecord *> * __nonnull records) {
     for (WKWebsiteDataRecord *record  in records) {
       if ( [record.displayName containsString:@"facebook"]) {
         [[WKWebsiteDataStore defaultDataStore]
             removeDataOfTypes:record.dataTypes
             forDataRecords:@[record]
             completionHandler:^{
               NSLog(@"Cookies for %@ deleted successfully",record.displayName);
             }
         ];
       }
     }
   }
 ];

Above snippet will sure work for iOS 9 and later. Unfortunately if we use WKWebView for iOS versions before iOS 9, we still have to stick to traditional method and delete the whole cookies storage as below.

NSString *libraryPath = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *cookiesFolderPath = [libraryPath stringByAppendingString:@"/Cookies"];
NSError *errors;
[[NSFileManager defaultManager] removeItemAtPath:cookiesFolderPath error:&errors];

Below is Swift 3 version

let dataStore = WKWebsiteDataStore.default()
    dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { (records) in
        for record in records {
            if record.displayName.contains("facebook") {
                dataStore.removeData(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(), for: [record], completionHandler: {
                    print("Deleted: " + record.displayName);
                })
            }
        }
    }

And Swift 4:

let dataStore = WKWebsiteDataStore.default()
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
  dataStore.removeData(
    ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(),
    for: records.filter { $0.displayName.contains("facebook") },
    completionHandler: completion
  )
}

Answer 5

Supports iOS 11.0 and above

Following solution worked well for me:

Step 1. Remove Cookie from HTTPCookieStorage

Step 2. Fetch data records from WKWebsiteDataStore and delete them.

Step 3. Create a new WKProcessPool

Create a WKWebView Extension:

extension WKWebView {

    func cleanAllCookies() {
        HTTPCookieStorage.shared.removeCookies(since: Date.distantPast)
        print("All cookies deleted")

        WKWebsiteDataStore.default().fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
            records.forEach { record in
                WKWebsiteDataStore.default().removeData(ofTypes: record.dataTypes, for: [record], completionHandler: {})
                print("Cookie ::: \(record) deleted")
            }
        }
    }

    func refreshCookies() {
        self.configuration.processPool = WKProcessPool()
    }
}

Usage:

override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(true)
        webView.cleanAllCookies()
        webView.refreshCookies()
    }

Answer 6

In WKWebView having issue to write and read its taking some time , So when you fetch the cookie some time you will get updated cookie but sometime it will be old one, and you will get error on any server request. I was facing this issue in 3 Days ,

Solution: No need to store cookies in WKWebsiteDataStore.

Getting cookies:

Swift:

extension WKWebView {
private var httpCookieStore: WKHTTPCookieStore  { return WKWebsiteDataStore.default().httpCookieStore }
func getCookies(for domain: String? = nil, completion: @escaping ([String : Any])->())  {
        var cookieDict = [String : AnyObject]()
        httpCookieStore.getAllCookies { cookies in
            for cookie in cookies {
                if let domain = domain {
                    if cookie.domain.contains(domain) {
                        cookieDict[cookie.name] = cookie.properties as AnyObject?
                    }
                } else {
                    cookieDict[cookie.name] = cookie.properties as AnyObject?
                }
            }
            completion(cookieDict)
        }
    }
}

Objective-c :

-(void )getAllCookies
{
    NSMutableString *updatedCockies= [[NSMutableString alloc] init];
    if (@available(iOS 11.0, *)) {
        WKHTTPCookieStore *cookieStore = _webView.configuration.websiteDataStore.httpCookieStore;
        NSLog(@"cookieStore *********************: %@",cookieStore);
        [cookieStore getAllCookies:^(NSArray* cookies) {
            NSHTTPCookie *cookie;
            for(cookie in cookies){
               NSLog(@"%@",cookie)
            }
            self->updatedCookie = updatedCockies;
            NSLog(@"cookie *********************: %@", self->updatedCookie);
        }];
    }
}

Every time you want new cookie so you need to write below code: Given Sharpio

Swift :

let config = WKWebViewConfiguration()
if #available(iOS 9.0, *) {
    config.websiteDataStore = WKWebsiteDataStore.nonPersistentDataStore()
} else {
     // I have no idea what to do for iOS 8 yet but this works in 9.
}

let webView = WKWebView(frame: .zero, configuration: config)

Objective C--

WKWebViewConfiguration *wkWebConfig = [WKWebViewConfiguration new];
    wkWebConfig.websiteDataStore = [WKWebsiteDataStore nonPersistentDataStore];


self.webView = [[WKWebView alloc] initWithFrame: CGRectZero
                                      configuration: wkWebConfig];

*******Every time you will get new cookies********
