UIWebView的启用cookies(UIWebview enable cookies)

我试图访问过需要使用Cookie特定的URL UIWebView但我不能访问它，因为Cookie被停用。所以，我做了以下内容：

启用Cookie：

 NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage]; [cookieStorage setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];

创建NSURLConnection和响应中提取的cookie：

 NSArray *cookies = [ NSHTTPCookie cookiesWithResponseHeaderFields: [ httpResponse allHeaderFields ] forURL:response.URL]; [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies: cookies forURL: response.URL mainDocumentURL:nil];

但无论是这并没有帮助。但是，如果我在Safari启动URL它成功加载之后，我可以加载在同一URL UIWebView了。你能帮我这个问题，我怎样可以使饼干UIWebView ？

提前致谢

创建后NSURLRequest ，在sharedHTTPCookieStorage所有Cookie复制到NSURLRequest ：

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPShouldHandleCookies:YES];
[self addCookies:cookies forRequest:request];
[_webView loadRequest:request];

并添加addCookies:forRequest方法

- (void)addCookies:(NSArray *)cookies forRequest:(NSMutableURLRequest *)request
{
    if ([cookies count] > 0)
    {
        NSHTTPCookie *cookie;
        NSString *cookieHeader = nil;
        for (cookie in cookies)
        {
            if (!cookieHeader)
            {
                cookieHeader = [NSString stringWithFormat: @"%@=%@",[cookie name],[cookie value]];
            }
            else
            {
                cookieHeader = [NSString stringWithFormat: @"%@; %@=%@",cookieHeader,[cookie name],[cookie value]];
            }
        }
        if (cookieHeader)
        {
            [request setValue:cookieHeader forHTTPHeaderField:@"Cookie"];
        }
    }
}
