Answer 1

我想它应该如何工作。

下面的代码对我来说工作正常。

 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
      }
