用户朋友在Facebook Sdk Graph Api v2中显示空白列表

Question

我已经将图表Api的版本更新为v2 。 现在我面临的问题是，当我执行以下代码时，它显示了空数组：

FBRequest *friendsRequest = [FBRequest requestForMyFriends];
        [friendsRequest startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *result, NSError *error) {
            NSArray *friendshipid;
            NSString *username;
            if (!error) {
                NSLog(@"friends = %@", [result description]);

            }
            if (completion) {
                completion(friendshipid, username, error);
            }
        }];
    }
}

我知道facebook sdk为用户朋友做了一些更改，现在它必须获得user_friends的许可 ，但是我不知道在哪里进行更改以请求user_friends的 许可

您可以使用给定的代码段。 在这里，我使用了“ Social Framework类”来获取Facebook friends 。 希望它对您有用。

- (void) connectWithFacebookFriends
{
    ACAccountStore *accountStore = [[ACAccountStore alloc] init];

    ACAccountType *accountTypeFacebook = [accountStore accountTypeWithAccountTypeIdentifier:
     ACAccountTypeIdentifierFacebook];

    NSDictionary *options = @{ACFacebookAppIdKey: kFaceBookId,
                              ACFacebookPermissionsKey: @[@"user_friends"],
                              ACFacebookAudienceKey: ACFacebookAudienceFriends
                              };

    [accountStore requestAccessToAccountsWithType:accountTypeFacebook
                                          options:options
                                       completion:^(BOOL granted, NSError *error)
    {
        if(granted) {

            NSArray *accounts = [accountStore
                                 accountsWithAccountType:accountTypeFacebook];
            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 performRequestWithHandler:^(NSData *responseData,
                                         NSHTTPURLResponse *urlResponse, NSError *error)
             {

                 NSString * str = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
                 DLog(@"%@",str);


                 NSLog(@"Request failed, %@", [urlResponse description]);
             }];
        } else {
            NSLog(@"Access Denied");
            NSLog(@"[%@]",[error localizedDescription]);

        }
    }];

}
