php - NSHTTPURLRequest can't read statusCode -

just doing normal http post nsmutableurlrequest , sendasynchronousrequest. nshttpurlresponse object pass in has statuscode of 0 after call. error:

sendasynchronousrequest error = error domain=nsurlerrordomain code=-1005 "the network connection lost." userinfo=0xb374a00 {nserrorfailingurlstringkey=http://54.221.224.251, nserrorfailingurlkey=http://54.221.224.251, nslocalizeddescription=the network connection lost., nsunderlyingerror=0xb587990 "the network connection lost."} 2013-09-04 16:46:19.146 panic[2032:5907] statuscode: 0

but no status code. why? status code server sending 150.

when post different data server, , don't ask return statuscode, connection goes smoothly , expected.

app code:

[nsurlconnection sendasynchronousrequest:request queue:queue completionhandler:^(nsurlresponse *response, nsdata *data, nserror *error) {             if (error)                 nslog(@"sendasynchronousrequest error = %@", error);                 nshttpurlresponse *httpresponse = (nshttpurlresponse *)response;                 int code = [httpresponse statuscode];                 nsstring *coder = [nsstring stringwithformat:@"%d",code];                 nslog(@"%@",coder);               if (data) {                 nslog(@"this data: %@",data);                 nshttpurlresponse *httpresponse = (nshttpurlresponse *)response;                 int code = [httpresponse statuscode];                 nsstring *coder = [nsstring stringwithformat:@"%d",code];                 nslog(@"%@",coder);             }         }];

sendresponse function

function sendresponse($status, $body = '', $content_type = 'text/html') {     $status_header = 'http/1.1 ' . $status . ' ' . 'error';     header($status_header);     header('content-type: ' . $content_type);     echo $body; } 

1xx status codes special (see http://greenbytes.de/tech/webdav/draft-ietf-httpbis-p2-semantics-23.html#status.1xx); also, it's not idea make new status codes.
