iOS: How can i receive HTTP 401 instead of -1012 NSURLErrorUserCancelledAuthentication

Solution
Yes. Stop using the synchronous API. If you use the asynchronous delegate-based API then you have a lot more control over the connection. With this API, except in cases where an error is encountered before the HTTP header is received, you will always receive `-connection:didReceiveResponse:`, which gives you access to the HTTP header fields (encapsulated in an `NSURLResponse` object). You can also implement authentication using the relevant delegate methods if you are so inclined.
Problem
I have a problem similar to the one described in the link below. NSHTTPURLResponse statusCode is returning zero when it should be 401 I use `[NSURLConnection sendSynchronousRequest:returningResponse:error:]` to get data from a server. When NSURLConnection receives the HTTP Code 401, it does not return anything but an error object with code `-1012` from the NSURLErrorDomain. `-1012` corresponds to `NSURLErrorUserCancelledAuthentication`. Since I have to parse the HTTP Header I need to get the original error and not what NSURLConnection made out of it. Is there a way to receive the original 401 http packet?
