如何使用AFNetworking获取重定向的URL？

Question

我使用AFNetworking get方法，网址类似于：

http://www.hi-pda.com/forum/redirect.php?from=notice&goto=findpost&pid=31089630&ptid=1631932

使用chrome我可以看到真正的URL是：

就在这个位置。

如何在使用AFNetworking时获取网址，我尝试了以下方法，它不起作用

[
    manager GET:threadNotice.URLString
    parameters:nil
    success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"%@",[operation.response allHeaderFields]);
    }
    failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    }
];

回复是

2015-05-31 00:11:03.349 HiPDA V2[20006:751020] {
    Connection = "keep-alive";
    "Content-Encoding" = gzip;
    "Content-Type" = "text/html";
    Date = "Sat, 30 May 2015 16:10:59 GMT";
    Server = "nginx/1.6.2";
    "Transfer-Encoding" = Identity;
    "X-Powered-By" = "PHP/5.3.10";
}

没有位置字段，我该怎么做？谢谢。

我用以下方法解决了答案：

AFHTTPRequestOperation *requestOperation=[[AFHTTPRequestOperation alloc] initWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:_URLString]]];
    [requestOperation setRedirectResponseBlock:^NSURLRequest *(NSURLConnection *connection, NSURLRequest *request, NSURLResponse *redirectResponse) {
        if (redirectResponse) {
            //this is the redirected url
            NSLog(@"%@",request.URL);
        }
        return request;
    }];
    [requestOperation start];
