使用來獲取Cookie UIWebView似乎很簡單NSHTTPCookieStorage.sharedHTTPCookieStorage()，它似乎WKWebView將Cookie存儲在其他位置。我做了一些研究，然后從NSHTTPURLResponse對象中獲取了一些Cookie 。但是，其中不包含WKWebView：func webView(webView: WKWebView, decidePolicyForNavigationResponse navigationResponse: WKNavigationResponse, decisionHandler: (WKNavigationResponsePolicy) -> Void) {  if let httpResponse = navigationResponse.response as? NSHTTPURLResponse {    if let headers = httpResponse.allHeaderFields as? [String: String], url = httpResponse.URL {      let cookies = NSHTTPCookie.cookiesWithResponseHeaderFields(headers, forURL: url)      for cookie in cookies {        logDebug(cookie.description)        logDebug("found cookie " + cookie.name + " " + cookie.value)      }    }  }}奇怪的是WKWebsiteDataStore，ios 9中還有一個類負責管理中的cookie WKWebView，但是，該類不包含檢索cookie數據的公共方法：let storage = WKWebsiteDataStore.defaultDataStore()storage.fetchDataRecordsOfTypes([WKWebsiteDataTypeCookies], completionHandler: { (records) -> Void in  for record in records {    logDebug("cookie record is " + record.debugDescription)    for dataType in record.dataTypes {      logDebug("data type is " + dataType.debugDescription)      // get cookie data??    }  }})是否有解決方法來獲取Cookie數據？
