如何删除WKWebview cookie

Question

现在我这样做

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

但它不适用于iOS 8,64位设备.

WKWebview干净的其他任何方式？任何帮助将不胜感激.谢谢.

Answer 1

Apple发布了适用于iOS 9的新API ,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);
             }
         ];
       }
     }
   }
 ];

上面的代码片段肯定适用于iOS 9及更高版本.不幸的是,如果我们在iOS 9之前使用WKWebView for iOS版本,我们仍然必须坚持使用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];

下面是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);
                })
            }
        }
    }

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 { $0.displayName.contains("facebook") },
    completionHandler: completion
  )
}

Answer 2

Swift 3版本的Sarat的答案:

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);
            })
        }
    }
}

Answer 3

支持 iOS 11.0 及以上

以下解决方案对我来说效果很好：

步骤 1. 从 HTTPCookieStorage

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

步骤 3. 创建一个新的 WKProcessPool

创建一个 WKWebView 扩展：

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()
    }
}

用法：

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

Answer 4

这些选项都不适合我，但我找到了一个：

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)

在iOS9中:

//// Optional data
NSSet *websiteDataTypes
= [NSSet setWithArray:@[
                        WKWebsiteDataTypeDiskCache,
                        //WKWebsiteDataTypeOfflineWebApplicationCache,
                        WKWebsiteDataTypeMemoryCache,
                        //WKWebsiteDataTypeLocalStorage,
                        //WKWebsiteDataTypeCookies,
                        //WKWebsiteDataTypeSessionStorage,
                        //WKWebsiteDataTypeIndexedDBDatabases,
                        //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");
}];
