如果您在计算机上将新闻分享到 Facebook，您可以选择为“特定的人或列表”分享。

我只需要从我的 iOS 应用分享照片给一些 friend 。

是否可以使用 Graph API 从应用中只为“特定的人或列表”分享新闻？

最佳答案

使用社交框架在用户墙上发帖

在 ACFacebookAudienceKey 中，选择其中一个

1.ACFacebookAudienceEveryone

2.ACFacebookAudienceFriends

3.ACFacebookAudienceOnlyMe

ACAccountStore *accountStore = [[ACAccountStore alloc] init];

ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook]; NSLog(@"0");

[accountStore requestAccessToAccountsWithType:accountType options:@{ACFacebookAppIdKey : @"00000000000", ACFacebookPermissionsKey : @"publish_stream", ACFacebookAudienceKey : ACFacebookAudienceFriends} completion:^(BOOL granted, NSError *error) {
    if(granted) {
        NSLog(@"1");
        NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];
        NSLog(@"2");
        if ([accountsArray count] > 0) {
            NSLog(@"3");
            ACAccount *facebookAccount = [accountsArray objectAtIndex:0];
            NSLog(@"4");
            SLRequest *facebookRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                                            requestMethod:SLRequestMethodPOST
                                                                      URL:[NSURL URLWithString:@"https://graph.facebook.com/me/feed"]
                                                               parameters:[NSDictionary dictionaryWithObject:post forKey:@"message"]];
            NSLog(@"5");

            [facebookRequest setAccount:facebookAccount];
            NSLog(@"6");

            [facebookRequest performRequestWithHandler:^(NSData* responseData, NSHTTPURLResponse* urlResponse, NSError* error) {
                NSLog(@"%@", [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]);
            }];


        }
    }
}];

用于发布到 friend 的墙上。
