afnetworking -- redirect url nsurlrequest: how handle redirected post? get lastly redirected url in ios 5? iphone nsurl lastly redirected url

my code sniplet taken answers:

afhttprequestoperationmanager *manager = [afhttprequestoperationmanager manager]; nsstring *urlstring = @"url"; nsdictionary *parameters = @{@"k1": @"v1", @"k2": @"v2"}; nsmutableurlrequest *request_orig = [manager.requestserializer requestwithmethod:@"get" urlstring:[[nsurl urlwithstring:urlstring relativetourl:manager.baseurl] absolutestring] parameters:parameters error:nil]; afhttprequestoperation *operation = [[afhttprequestoperation alloc] initwithrequest:request_orig]; [operation setcompletionblockwithsuccess:^(afhttprequestoperation *operation, id responseobject) { //this first redirect url receive nslog(@"new redirect url: %@",[[[operation response] url] absolutestring]); } failure:^(afhttprequestoperation *operation, nserror *error) { nslog(@"failure: err: %@", error); }]; [operation setredirectresponseblock:^nsurlrequest *(nsurlconnection *connection, nsurlrequest *request, nsurlresponse *redirectresponse) { if (redirectresponse) { nsmutableurlrequest *r = [request_orig mutablecopy]; // original request [r seturl: [request url]]; homecoming r; } else { nslog(@"redirecting : %@", [request url]); homecoming request; } }]; [manager.operationqueue addoperation:operation];

i able receive first redirected url there no 2nd or 3rd redirect after that. should in order allow redirects go on , receive url lastly redirect made. novice in ios dev. i'll appreciate help. thanks.

if want follow redirects, sufficient maintain returning provided request , abort when info starting come through connection.

i wrote time ago osx, should work on ios (w/ arc) without changes:

- (nsurl *)resolvedurlredirectionsforurl:(nsurl *)aurl { nslog(@"started w/ initial url: '%@'", aurl); nsurl *originalurl = aurl; nsurl __block *resolvedurl = nil; if (aurl) { dispatch_semaphore_t __communicationlock = dispatch_semaphore_create(0); nsurlrequest *resolverequest = [nsurlrequest requestwithurl:originalurl cachepolicy:nsurlrequestreloadignoringlocalandremotecachedata timeoutinterval:5. ]; afhttprequestoperation *request = [[afhttprequestoperation alloc] initwithrequest:resolverequest]; [request setredirectresponseblock:^nsurlrequest *(nsurlconnection *connection, nsurlrequest *request, nsurlresponse *redirectresponse) { nslog(@"..request encountered redirection to: '%@'",request.url); if (redirectresponse) resolvedurl = [request.url copy]; homecoming request; }]; afhttprequestoperation __weak *weakrequest = request; [request setdownloadprogressblock:^(nsuinteger bytesread, long long totalbytesread, long long totalbytesexpectedtoread) { [weakrequest cancel]; }]; [request setcompletionblockwithsuccess:^(afhttprequestoperation *operation, id responseobject) { nslog(@"..request successful! (result: %@)",responseobject); dispatch_semaphore_signal(__communicationlock); } failure:^(afhttprequestoperation *operation, nserror *error) { if (operation.response.statuscode == 200) nslog(@"..request successful! (aborted)"); else nslog(@"..request failed! (error: %@)",error); dispatch_semaphore_signal(__communicationlock); }]; [request start]; dispatch_semaphore_wait(__communicationlock, dispatch_time_forever); } nslog(@"resolved url '%@' '%@'",originalurl,resolvedurl); homecoming resolvedurl; }

note: because of semaphore it's not thought run on main thread unaltered it'll block main runloop (and nsurlconnections hate that). hence improve dispatch method phone call global queue.
