ios - objective-c how to us NSURLSession with AFNetworking -

i have code here logins me url, issue when try remove creds not working, found solution online:

http://www.ciiycode.com/0yhhmexwguqq/using-nsurlcredentialpersistenceforsession-while-request-and-then-clearing-the-credentials-on-logout-still-persist-the-cerdentials

if you're using nsurlsession, invalidate session , create new one, e.g.:  [self.session invalidateandcancel]; self.session = [nsurlsession sessionwithconfiguration:[nsurlsessionconfiguration defaultsessionconfiguration] delegate:self delegatequeue:nil]; clear session-scoped credentials. 

so question is, can use nsurlsession afnetworking:

nsurl *url = [nsurl urlwithstring:kip];    nsurlrequest *request = [nsurlrequest requestwithurl:url];       afhttprequestoperation *operation = [[afhttprequestoperation alloc]                                          initwithrequest:request];      nsurlcredential *credential = [nsurlcredential                                    credentialwithuser:user                                    password:password                                    persistence:nsurlcredentialpersistenceforsession];       [operation setcredential:credential];     [[nsoperationqueue mainqueue] addoperation:operation];       [operation setcompletionblockwithsuccess:^(afhttprequestoperation *operation, id responseobject) {          if (completionhandler) {             completionhandler(responseobject, nil);         }      } failure:^(afhttprequestoperation *operation, nserror *error) {          if (completionhandler) {             completionhandler(nil, error);         }      }];      [operation start]; 

update

i got started on this:

nsurl *url = [nsurl urlwithstring:kip];      nsurlsessionconfiguration *sessionconfiguration = [nsurlsessionconfiguration defaultsessionconfiguration];      afurlsessionmanager *manager = [[afurlsessionmanager alloc] initwithsessionconfiguration:sessionconfiguration];      [manager setresponseserializer:[afjsonresponseserializer serializer]];     nsurlrequest *request = [nsurlrequest requestwithurl:url];      [[manager datataskwithrequest:request completionhandler:^(nsurlresponse *response, id responseobject, nserror *error) {         if (completionhandler) {             completionhandler(responseobject, nil);         }     }] resume]; 

how add username , password this?

try using afnsurlsession instead of afhttprequestoperation. in afnsurlsession can supply block delegate setsessiondidreceiveauthenticationchallengeblock can provide necessary credential.

from afnsurlsession.h:

/**  sets block executed when connection level authentication challenge has occurred, handled `nsurlsessiondelegate` method `urlsession:didreceivechallenge:completionhandler:`.  @param block block object executed when connection level authentication challenge has occurred. block returns disposition of authentication challenge, , takes 3 arguments: session, authentication challenge, , pointer credential should used resolve challenge.  */ - (void)setsessiondidreceiveauthenticationchallengeblock:(nsurlsessionauthchallengedisposition (^)(nsurlsession *session, nsurlauthenticationchallenge *challenge, nsurlcredential * __autoreleasing *credential))block;
