                if (newCookie !=nil) {

                    [newCookieArr addObject:newCookie];

//注入cookie

                    [sharedHTTPCookieStorage setCookies:newCookieArr forURL:[NSURL URLWithString:self.financeUrl] mainDocumentURL:nil];

                }

            }

        }

    }

注：注入cookie需在加载URL之前有效。
