iphone facebookpublishToStream问题

Question

我正在使用 iOS facebook DemoApp 示例发布到我的个人资料。它工作得很好。我的问题是如何在这篇文章中添加图片链接？我使用的代码是：

- (IBAction)publishStream:(id)sender 
{   
    SBJSON *jsonWriter = [[SBJSON new] autorelease];

    NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:
                                                        @"title",@"text",
                                                        @"http://www.link.com/",@"href",
                                                        nil], nil];

    NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];
    NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
                                @"This is a name!", @"name",
                                @"This is a caption!", @"caption",
                                @"http://www.link.com/images/log1.png", @"picture",
                                @"This is a long description that goes on an on.", @"description",
                                @"http://www.link.com", @"href",                                
                                nil];

    NSString *attachmentStr = [jsonWriter stringWithObject:attachment];
    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   kAppId, @"api_key",
                                   @"Share on Facebook",  @"user_message_prompt",
                                   actionLinksStr, @"action_links",
                                   attachmentStr, @"attachment",
                                   nil];    

    [facebook dialog:@"stream.publish"
            andParams:params
          andDelegate:self];
}

图片不会出现。我使用的链接是正确的。并且帖子成功。我如何才能显示该图片链接？

感谢您的任何和所有帮助。
