如何删除 WKWebview cookie [英] How to delete WKWebview cookies

问题描述

现在我是这样做的

    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.

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

WKWebview 的干净 cookie 有什么其他方式吗?任何帮助将不胜感激.谢谢.

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

推荐答案

Apple 发布了用于 iOS 9 的新 API，因此现在我们可以删除为 <存储的域特定 cookiestrong>WKWebView 使用以下代码，但这仅适用于iOS 版本 9 或 稍后:

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);
             }
         ];
       }
     }
   }
 ];

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cookies存储如下.

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];

以下是 Swift 3 版本

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);
                })
            }
        }
    }

和 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
  )
}
