iphone - 发布图片不再适用于新的 iOS Facebook SDK

Question

我添加了在 iOS6 上运行良好的功能，但在 iOS7 中，我不得不更新 Facebook SDK，因为旧版本中的 id 和 setId 被标记为非公开且未经验证。所以，我用新的 SDK 替换了旧的 SDK，但是，当然，帖子图像不再有效（因为 id 肯定是未知的）。我有这个：

[params setObject:textViewMessageFacebook.text forKey:@"message"];
[params setObject:UIImagePNGRepresentation(screenshot) forKey:@"picture"];

[FBRequestConnection startWithGraphPath:[NSString stringWithFormat:@"%@/photos", idAmiS]
                             parameters:params
                             HTTPMethod:@"POST"
                      completionHandler:^(FBRequestConnection *connection,
                                          id result,
                                          NSError *error)

但不知道如何纠正它以使其正常工作......谢谢

使用 SlComposer 控制器在 facebook 上发布图像。

1）首先您将社交框架和帐户框架添加到您的项目中，然后尝试以下代码

把这段代码写在你想要的地方......

    {
    ACAccountType *facebookTypeAccount = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];


        [accountStore requestAccessToAccountsWithType:facebookTypeAccount
                                               options:@{ACFacebookAppIdKey: @"131740927031850", ACFacebookPermissionsKey: @[@"email"]}
                                            completion:^(BOOL granted, NSError *error) {
                                                if(granted){
                                                    NSArray *accounts = [accountStore accountsWithAccountType:facebookTypeAccount];
                                                    _facebookAccount = [accounts lastObject];
                                                    ACAccountCredential *fbCredential = [_facebookAccount credential];
                                                    accessToken = [fbCredential oauthToken];
                                                    NSLog(@"Facebook Access Token: %@", accessToken);
                                                    NSLog(@"Success");

                                                    [self facebook];
                                                }else{

                                                }
                                            }];

        if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
        {
            SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
            [tweetSheet setInitialText:@"posting from my own app! :)"];
            [tweetSheet addURL:[NSURL URLWithString:@"www.xyz.com"]];


// Here you add the image

             [tweetSheet addImage:[UIImage imageNamed:@"yourimage.png"]];




            [self presentViewController:tweetSheet animated:YES completion:nil];


        }
        else
