Answer 1

Pomyślałem, jak to powinno działać.

Poniższy kod działa dobrze dla mnie.

NSArray *accounts = [accountStore 
           accountsWithAccountType:facebookAccountType]; 
      ACAccount *facebookAccount = [accounts lastObject]; 
      NSString *acessToken = [NSString stringWithFormat:@"%@",facebookAccount.credential.oauthToken]; 
      NSDictionary *parameters = @{@"access_token": acessToken}; 
      NSURL *feedURL = [NSURL URLWithString:@"https://graph.facebook.com/me/friends"]; 
      SLRequest *feedRequest = [SLRequest 
            requestForServiceType:SLServiceTypeFacebook 
            requestMethod:SLRequestMethodGET 
            URL:feedURL 
            parameters:parameters]; 
      feedRequest.account = facebookAccount; 
      [feedRequest performRequestWithHandler:^(NSData *responseData, 
                NSHTTPURLResponse *urlResponse, NSError *error) 
      { 
       NSLog(@"%@",[[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]); 
      }]; 
     } 
     else 
     { 
      // Handle Failure 
     }

-(void)getFacebookFriendsList 
{ 
    if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) 
    { 
     ACAccountStore *store = [[ACAccountStore alloc] init]; 

     ACAccountType *facebookTypeAccount = [store accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook]; 
     //Replace with your Facebook.com app ID 
     NSDictionary *options = @{ACFacebookAppIdKey:kFacebookAppID, ACFacebookPermissionsKey:@[@"email", @"read_friendlists"], 
            ACFacebookAudienceKey:ACFacebookAudienceFriends}; 

     [store requestAccessToAccountsWithType:facebookTypeAccount 
             options:options 
            completion:^(BOOL granted, NSError *error){ 

             if(granted) 
             { 
              NSArray *accounts = [store accountsWithAccountType:facebookTypeAccount];

                { 
                 // if error occured e.g. Invalid Auth etc.
