Question

我有一个应用程序即时上传照片，我试图添加上传到用户Facebook粉丝页面（他们管理）的功能。

我遇到的问题是我可以成功将照片上传到粉丝页面，但它没有显示在粉丝页面的时间轴上，它只显示在＆下＃34;其他人的近期帖子＆＃34;粉丝页面的一部分。

我显然没有正确上传这些图片。这是我的代码：

ACAccountType * accountType = [_accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
        [_accountStore requestAccessToAccountsWithType:accountType options:@{ACFacebookAppIdKey: @"XXXXXXXXXXXX", ACFacebookPermissionsKey : @[@"photo_upload",@"publish_stream", @"publish_actions", @"manage_pages"], ACFacebookAudienceKey : ACFacebookAudienceEveryone} completion:^(BOOL granted, NSError *error) {
            if (granted) {

                NSArray * accounts = [_accountStore accountsWithAccountType:accountType];

                NSDictionary *fanPages = [[NSUserDefaults standardUserDefaults] objectForKey:FACEBOOK_PREF_FAN_PAGES_IDS];

                //if using fan pages
                if (fanPages.count)
                {

                    for (id key in fanPages) {
                        //id is the key and the access token is the value
                        NSLog(@"access token:%@, fanpage id: %@", fanPages[key], key);

                        NSMutableString *requestURL = [NSMutableString stringWithFormat:@"https://graph.facebook.com/%@/photos/", key];

                        NSURL * url = [NSURL URLWithString:requestURL];

                        NSDictionary *parameters = @{@"access_token": [fanPages[key] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding], @"no_story":@"0", @"message": hashtags};

                        SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodPOST URL:url parameters:parameters];

                        [request addMultipartData:UIImageJPEGRepresentation(image, 0.9) withName:@"source" type:@"application/octet-stream" filename:@"media.png"];
                        //NSLog(@"%@",[accounts lastObject]);
                        [request setAccount:[accounts lastObject]];

                        //make request
                        [request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
                            NSLog(@"uploaded for %@",fanPages[key]);

                            NSString *respData = [[NSString alloc] initWithData:responseData
                                                                       encoding:NSUTF8StringEncoding];

                            NSLog(@"responseData %@",respData);
                            NSLog(@"urlResponse for %@",urlResponse);


                            [self performSelectorOnMainThread:@selector(removeProgressView) withObject:nil waitUntilDone:NO];

                        }];

                    }



                }
                else
                {
                    //upload to personal timeline
                    NSURL * url = [NSURL URLWithString:@"https://graph.facebook.com/me/photos"];
                    SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodPOST URL:url parameters:nil];
                    [request addMultipartData:[hashtags dataUsingEncoding:NSUTF8StringEncoding] withName:@"message" type:@"multipart/form-data" filename:nil];
                    [request addMultipartData:UIImageJPEGRepresentation(image, 0.9) withName:@"source" type:@"application/octet-stream" filename:@"media.png"];
                    [request setAccount:[accounts lastObject]];
                    [request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
                        [self performSelectorOnMainThread:@selector(removeProgressView) withObject:nil waitUntilDone:NO];
                    }];
                }

            } else {

                //theres an error or they are not granted

            }

关于我做错什么的任何想法？我已经在互联网上搜索了好几天，一切看起来都是正确的。

事实证明我正在做的一切正确，问题是如果我离开了：

[request setAccount:[accounts lastObject]];

这导致它代表我发布，不会出现在时间轴中。删除此代码可以解决问题，我的所有帖子现在都显示在粉丝页面时间轴上，而不是来自我的Facebook用户帐户。

谢谢Tobi，我知道这是访问令牌，我以为我正确地传递了它，显然我不是。

所以只是为了重新迭代，在发布到粉丝页面时不要使用setAccount，因为它会用你的用户令牌而不是粉丝页面令牌覆盖access_token。
