清除WKWebView cookies的方法

在UIWebView下，可以使用

[[NSURLCache sharedURLCache] removeAllCachedResponses];//清除缓存

WKWebView清除cookies的方法（iOS9以上）

WKWebsiteDataStore *dateStore = [WKWebsiteDataStore defaultDataStore];
  [dateStore fetchDataRecordsOfTypes:[WKWebsiteDataStore allWebsiteDataTypes]
           completionHandler:^(NSArray<WKWebsiteDataRecord *> * __nonnull records) {
             for (WKWebsiteDataRecord *record in records)
             {
//               if ( [record.displayName containsString:@"baidu"]) //取消备注，可以针对某域名清除，否则是全清
//               {
                 [[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:record.dataTypes
                                      forDataRecords:@[record]
                                    completionHandler:^{
                                      NSLog(@"Cookies for %@ deleted successfully",record.displayName);
                                    }];
//               }
             }
           }];

iOS9一下用这种方法：

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

查看cookie

NSHTTPCookie *cookie;
NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [cookieJar cookies]) {
  NSLog(@"%@", cookie);
}
