In order for me to get the progress, I need the totalBytesExpectedToRead value, but it's giving me a -1. I checked the headers of the HTTP response and the content length is there...
{
"Cache-Control" = "no-store, no-cache, must-revalidate, post-check=0, pre-check=0";
Connection = "Keep-Alive";
"Content-Encoding" = gzip;
"Content-Length" = 36902;
"Content-Type" = "text/plain";
Date = "Sat, 03 Mar 2012 23:53:11 GMT";
Expires = "Thu, 19 Nov 1981 08:52:00 GMT";
"Keep-Alive" = "timeout=5, max=95";
"Last-Modified" = "Sat, 03 Mar 2012 23:53:11 GMT";
Pragma = "no-cache";
Server = "Apache/2.2.20 (Ubuntu)";
Vary = "Accept-Encoding";
"X-Powered-By" = "PHP/5.3.6-13ubuntu3.3";

这是AFNetworking框架的问题吗?
