Ich habe 3 Methoden, UserLogin, Login und LogoutButtonPressed:

UserLogin: Ich verwende AFNetworking, um mithilfe von NSURLCredential eine Verbindung zu einer Windows-authentifizierten URL herzustellen:

-(void)UserLogin:(NSString *)user andPassWordExists:(NSString *)password completionHandler:(void (^)(NSArray *resultsObject, NSError *error))completionHandler
{

   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];

}

Diese Methode wird von der Login-Methode aufgerufen:

- (void)Login
{
    NSString *rawString = [self.idTextField text];
    NSCharacterSet *whitespace = [NSCharacterSet whitespaceAndNewlineCharacterSet];
    [self.idTextField setText:[rawString stringByTrimmingCharactersInSet:whitespace]];


    [userName UserLogin:self.idTextField.text andPassWordExists:self.passwordTextField.text completionHandler:^(id responseObject, NSError *error) {
        if (responseObject) {

                [self.idTextField removeFromSuperview];
                [self.passwordTextField removeFromSuperview];
                [self.loginButton removeFromSuperview];
                self.idTextField = nil;
                self.passwordTextField = nil;
                //self.loginButton = nil;


                [self CreateMenu];



                [indicatorView stopAnimating];
                [indicatorView removeFromSuperview];
                indicatorView = nil;
                [loadingView removeFromSuperview];
                loadingView = nil;
        }else{


            [self CustomAlert:@"Sorry Login Failed, User and/or Passsword Incorrect"];

            [indicatorView stopAnimating];
            [indicatorView removeFromSuperview];
            indicatorView = nil;
            [loadingView removeFromSuperview];
            loadingView = nil;

        }
    }];

}

Und ich versuche, meine Sitzung mit dem LogoutButtonPressed zu löschen:

- (void)LogoutButtonPressed
{

    //@TODO: Fix Logout

    NSDictionary *credentialsDict = [[NSURLCredentialStorage sharedCredentialStorage] allCredentials];

    if ([credentialsDict count] > 0) {
        NSEnumerator *protectionSpaceEnumerator = [credentialsDict keyEnumerator];
        id urlProtectionSpace;

        while (urlProtectionSpace = [protectionSpaceEnumerator nextObject]) {
            NSEnumerator *userNameEnumerator = [[credentialsDict objectForKey:urlProtectionSpace] keyEnumerator];
            id userNameCred;

            while (userNameCred = [userNameEnumerator nextObject]) {
                NSURLCredential *cred = [[credentialsDict objectForKey:urlProtectionSpace] objectForKey:userNameCred];
                NSLog(@"cred to be removed: %@", cred);
                [[NSURLCredentialStorage sharedCredentialStorage] removeCredential:cred forProtectionSpace:urlProtectionSpace];
            }
        }
    }
}

Ich habe diesen Code aus diesem Beispiel erhalten:http: //www.springenwerk.com/2008/11/i-am-currently-building-iphone.htm

Nun habe ich das Problem, dass ich mich immer noch anmelden kann, wenn ich die Abmeldeschaltfläche auslöse und dann die Anmeldemethode auslöse. Wenn ich mich abmelde, dann warte ich 2-3 Minuten und melde mich mit KEINEN ABMELDUNGEN an. Ich kann mich nicht anmelden. Warum verhält es sich so, es ist fast so, als ob die Creds noch gerettet sind. Bitte helfen Sie.

AKTUALISIERE

Ich habe versucht, den Cache, Cookies und Creds in meinem LogoutButtonPressed zu löschen:

NSURLCache *sharedCache = [NSURLCache sharedURLCache];
[sharedCache removeAllCachedResponses];

NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSArray *cookies = [cookieStorage cookies];
id cookie;
for (cookie in cookies) {
    [cookieStorage deleteCookie:cookie];
}

NSDictionary *credentialsDict = [[NSURLCredentialStorage sharedCredentialStorage] allCredentials];
if ([credentialsDict count] > 0) {
    NSEnumerator *protectionSpaceEnumerator = [credentialsDict keyEnumerator];
    id urlProtectionSpace;
    while (urlProtectionSpace = [protectionSpaceEnumerator nextObject]) {
        NSEnumerator *userNameEnumerator = [[credentialsDict objectForKey:urlProtectionSpace] keyEnumerator];
        id userNameCreds;
        while (userNameCreds = [userNameEnumerator nextObject]) {
            NSURLCredential *cred = [[credentialsDict objectForKey:urlProtectionSpace] objectForKey:userNameCreds];
            [[NSURLCredentialStorage sharedCredentialStorage] removeCredential:cred forProtectionSpace:urlProtectionSpace];
        }
    }
}

und es hat immer noch nicht funktioniert.

Ich habe auch versucht, AuthorizationHeader zu löschen und AllOperations abzubrechen, und immer noch nichts. Nach dem Abmelden kann ich mich immer noch mit falschen oder keinen creds anmelden:

NSURLCache *sharedCache = [NSURLCache sharedURLCache];
    [sharedCache removeAllCachedResponses];

    NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    NSArray *cookies = [cookieStorage cookies];
    id cookie;
    for (cookie in cookies) {
        [cookieStorage deleteCookie:cookie];
    }

    NSDictionary *credentialsDict = [[NSURLCredentialStorage sharedCredentialStorage] allCredentials];
    if ([credentialsDict count] > 0) {
        NSEnumerator *protectionSpaceEnumerator = [credentialsDict keyEnumerator];
        id urlProtectionSpace;
        while (urlProtectionSpace = [protectionSpaceEnumerator nextObject]) {
            NSEnumerator *userNameEnumerator = [[credentialsDict objectForKey:urlProtectionSpace] keyEnumerator];
            id userNameCreds;
            while (userNameCreds = [userNameEnumerator nextObject]) {
                NSURLCredential *cred = [[credentialsDict objectForKey:urlProtectionSpace] objectForKey:userNameCreds];
                [[NSURLCredentialStorage sharedCredentialStorage] removeCredential:cred forProtectionSpace:urlProtectionSpace];
            }
        }
    }

    NSURL *url = [NSURL URLWithString:kIP];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    AFHTTPRequestSerializer <AFURLRequestSerialization> * requestSerializer = manager.requestSerializer;
    [requestSerializer clearAuthorizationHeader];

    AFHTTPRequestOperationManager  *httpClient = [[AFHTTPRequestOperationManager  alloc] initWithBaseURL:url];
    [[httpClient operationQueue] cancelAllOperations];
