Get Facebook access token from Social.framework(iOS6)

Question

I need to retrieve Facebook access token of my system account, which I set in Settings application.

I know that Social.framework(iOS6) knows all my FB account information & I can perform API calls to Graph API using SLRequest class, like in this post http://blogs.captechconsulting.com/blog/eric-stroh/ios-6-tutorial-integrating-facebook-your-applications

But, my question is - how can I retrieve my Facebook system account's access token?

I found solution for Twitter https://dev.twitter.com/docs/ios/using-reverse-auth , but could you help me with Facebook

If you already know how to get the account store set up, here's code around it showing how to get the access token:

@property (strong, nonatomic) ACAccountStore *accountStore; @property (strong, nonatomic) ACAccount *fbAccount;  ...  @synthesize accountStore = _accountStore; @synthesize fbAccount = _fbAccount;  ...  // Initialize the account store self.accountStore = [[ACAccountStore alloc] init];  // Get the Facebook account type for the access request ACAccountType *fbAccountType = [self.accountStore     accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];  // Request access to the Facebook account with the access info [self.accountStore requestAccessToAccountsWithType:fbAccountType                                            options:fbInfo                                         completion:^(BOOL granted, NSError *error) {     if (granted) {         // If access granted, then get the Facebook account info         NSArray *accounts = [self.accountStore                              accountsWithAccountType:fbAccountType];         self.fbAccount = [accounts lastObject];          // Get the access token, could be used in other scenarios         ACAccountCredential *fbCredential = [self.fbAccount credential];                     NSString *accessToken = [fbCredential oauthToken];         NSLog(@"Facebook Access Token: %@", accessToken);           // Add code here to make an API request using the SLRequest class      } else {         NSLog(@"Access not granted");     } }];
