ios 如何删除 WKWebview cookie

How to delete WKWebview cookies

提问by Pankaj Gaikar

For now I am doing like this

现在我正在这样做

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

But it is not working on iOS 8, 64-bit device.

但它不适用于 iOS 8、64 位设备。

Any other way the clean cookies of WKWebview? Any help will be appreciated. thanks.

WKWebview的干净cookies还有其他方式吗？任何帮助将不胜感激。谢谢。

Apple released new APIs for iOS 9, so now we can remove domain specific cookies stored for WKWebViewwith below code, but this will only work on devices with iOSversion9orlater:

Apple 为iOS 9发布了新的 API ，因此现在我们可以使用以下代码删除为WKWebView存储的域特定 cookie ，但这仅适用于iOS 9或更高版本的设备：

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 9and later. Unfortunately if we use WKWebViewfor iOS versions before iOS 9, we still have to stick to traditional method and delete the whole cookies storage as below.

以上代码段肯定适用于iOS 9及更高版本。不幸的是，如果我们在iOS 9之前的 iOS 版本中使用WKWebView，我们仍然必须坚持传统方法并删除整个 cookie 存储，如下所示。

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

以下是 Swift 3 版本

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:

和斯威夫特 4：

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

Supports iOS 11.0 and above

Following solution worked well for me:

以下解决方案对我来说效果很好：

Step 1. Remove Cookie from HTTPCookieStorage

步骤 1. 从 HTTPCookieStorage

Step 2. Fetch data records from WKWebsiteDataStoreand delete them.

步骤 2. 从中获取数据记录WKWebsiteDataStore并删除它们。

Step 3. Create a new WKProcessPool

步骤 3. 创建一个新的 WKProcessPool

Create a WKWebView Extension:

创建一个 WKWebView 扩展：

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

Usage:

用法：

//// Optional data
NSSet *websiteDataTypes
= [NSSet setWithArray:@[
                        WKWebsiteDataTypeDiskCache,
                        //WKWebsiteDataTypeOfflineWebApplicationCache,
                        WKWebsiteDataTypeMemoryCache,

                        //WKWebsiteDataTypeWebSQLDatabases
                        ]];
//// All kinds of data
//NSSet *websiteDataTypes = [WKWebsiteDataStore allWebsiteDataTypes];
//// Date from
NSDate *dateFrom = [NSDate dateWithTimeIntervalSince1970:0];
//// Execute
[[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:websiteDataTypes modifiedSince:dateFrom completionHandler:^{
    // Done
    NSLog(@"remove done");

In iOS9:

在 iOS9 中：

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)

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

这些选项都不适合我，但我找到了一个：

                         for: records.filter { 
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

In addition to clearing cookies in the shared cookie storage, i'd try clearing the cache (NSURLCache) and discard the WKWebView and create a new one with a new WKProcessPool

除了清除共享 cookie 存储中的 cookie 之外，我还会尝试清除缓存 (NSURLCache) 并丢弃 WKWebView 并使用新的 WKProcessPool 创建一个新的

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 ,

在 WKWebView 中，写入和读取它需要一些时间，因此当您获取 cookie 时，您将获得更新的 cookie，但有时它会是旧的，并且您将在任何服务器请求上出错。我在 3 天内遇到了这个问题，

Solution: No need to store cookies in WKWebsiteDataStore.

解决方案：无需在 WKWebsiteDataStore 中存储 cookie。

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

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

每次您想要新的 cookie 时，您都需要编写以下代码：Given Sharpio

WKWebview storing nothing inside [NSHTTPCookieStorage sharedHTTPCookieStorage].

WKWebview 在 [NSHTTPCookieStorage sharedHTTPCookieStorage] 中不存储任何内容。

clearing WKWebsiteDataStorewill be the solution for this problem.

清除WKWebsiteDataStore将是此问题的解决方案。

Still for IOS8 which is using WKwebview, this method is not applicable..

还是对于使用WKwebview的IOS8，这个方法不适用..
