iphone - Facebook Connect iPhone 自定义发布流

Question

我刚刚下载了适用于 iOS 的 Facebook SDK，因为我需要能够将自定义流发布到用户的 Facebook 订阅源。示例应用程序有一个名为 publishStream:(id)sender 的方法，它似乎为“发布流”对话框设置自定义描述，但是当我的对话框出现时，我看到的只是一个开始输入的空对话框。示例中的代码应用程序是这样的:

`SBJSON *jsonWriter = [[SBJSON new] autorelease];

NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:
                                                       @"Always Running",@"text",@"http://itsti.me/",@"href", nil], nil];

NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];
NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
                            @"a long run", @"name",
                            @"The Facebook Running app", @"caption",
                            @"it is fun", @"description",
                            @"http://itsti.me/", @"href", nil];
NSString *attachmentStr = [jsonWriter stringWithObject:attachment];
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               @"Share on Facebook",  @"user_message_prompt",
                               actionLinksStr, @"action_links",
                               attachmentStr, @"attachment",
                               nil];


[_app.facebook dialog:@"feed"
        andParams:params
      andDelegate:self];`    

此代码是否应该填充自定义流？如果是这样，为什么演示项目不为我做这件事？如果没有，我需要采取哪些步骤才能使用自定义数据填充流？

谢谢你的帮助，

示例应用有点过时。阅读 Facebook 的 Feed Dialog documentation查看您可以设置的属性，然后像这样设置:

NSDictionary* params = [NSDictionary dictionaryWithObjectsAndKeys:
                                     @"Share on Facebook",  @"user_message_prompt",
                                     @"http://www.yoursitehere.com/", @"link",
                                     @"http://www.yoursitehere.com/thumbnail.jpg", @"picture",
                                     nil];


[self.facebook dialog:@"feed" andParams:params andDelegate:self];
