iOS浏览器错误-第3个Pary Cookie和iframe内容

Question

在iFrame中加载第三方Web应用程序。提供的用于处理Cookie的javascript代码在iOS浏览器中不起作用，请有人可以提供solutin：

<script language="javascript">
    (function() {
        if (typeof window.addEventListener !== "undefined") {
            window.addEventListener("message", messageReceived, false);
        }

        function messageReceived(e) {
            var data;
            if (e.origin !== "https://whitelabel-3rd-party.com") {
                return;
            }
            try {
                data = JSON.parse(e.data);
            } catch (err) {
                return;
            }
            if (typeof data !== "object" || typeof data.event !== "string" || typeof data.data === "undefined") {
                return;
            }
            if (data.event === "safariCookieFix") {
                window.location.href = e.origin + "/en-gb/cookiefix?redirectUrl=http(s)://www.mydomain.com/online-auction";
                return;
            }
        }
    })();
</script>
