Javascript 为什么iOS UIWebView视频不发送cookie？

我有一个UIWebView，并从我的网站加载一个html页面：

- (void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    [webView loadRequest:nsUrlRequest];
}

然后我想从webview加载一些图像/视频：

- (void)webViewDidFinishLoad:(UIWebView *)myView
{
        // this line I got video url
        NSString* videoUrl = XXXXX;

         // cookie is all right in the page
         [myView stringByEvaluatingJavaScriptFromString:@"alert(document.cookie)"];

        // image load request is correct with cookie
        [myView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.createElement('img').src='/Images/logo.png'"]];

        // but video request no cookie !!!!!
        [myView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"var video = document.createElement('video');video.src = '%@';video.autoPlay = true;", videoUrl]];

}

请帮帮我！！救救我

确保已在iPhone中为webview启用Cookie 尝试使用：

[NSHTTPCookieStorage sharedHTTPCookieStorage].cookieAcceptPolicy = 
    NSHTTPCookieAcceptPolicyAlways;

要发送cookie，请检查此堆栈链接：

cookie好的，在webview中，它只是不随视频请求发送，但图像请求可以……我添加了NSHTTPCookieAcceptPolicyAlways@ArielZhang试试这个NSArray*cookies=[[nshttpcookeStorage sharedhttpcookeStorage]cookies]；NSDictionary*headers=[NSHTTPCookie requestHeaderFieldsWithCookies:cookies]；[请求setAllHTTPHeaderFields:headers]；我如何获得请求？实际上，在我用javascript设置视频的src之后，视频的请求是调用服务器自动的。我在osx的webview中看到了同样的问题。你找到解决办法了吗？
