ios Facebook图形API-发布音频文件

我正在使用iOS中的FB Graph API在用户墙上发布。我想附加一个托管在其他地方的音频文件。由于“附件”似乎不再有效，我尝试将og:audio作为属性：

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

    NSString *fileURL = [NSString stringWithFormat:@"http://site-addr.com/%@", @"tst.mp3"];

    NSDictionary *properties = [NSDictionary dictionaryWithObjectsAndKeys:
                                fileURL, @"og:audio",
                                strText, @"og:audio:title", 
                                nil];

    NSString *propStr = [jsonWriter stringWithObject:properties];


    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"message Text",@"message",
                                   @"Martha",@"name",
                                   @"http://addr/something.jpg", @"picture",
                                   propStr, @"properties",
                                   nil];          

[facebook requestWithGraphPath:@"me/feed" andParams:params andHttpMethod:@"POST" andDelegate:self];

不知怎的，我得到的只是“og:audio”。。。。作为文本输入到帖子中。 我想知道如何将音频文件作为播放器发布到post中

-(void)postMeFeedButtonPressed{

    NSMutableDictionary *variables = [NSMutableDictionary dictionaryWithCapacity:4];

    [variables setObject:@"Sharing Audio" forKey:@"message"];
    [variables setObject:[NSString stringWithFormat:@"Audio from xyz" forKey:@"name"];
    [variables setObject:@"Audio URL here.mp3" forKey:@"source"];



    FbGraphResponse *fb_graph_response = [fbGraph doGraphPost:@"me/feed" withPostVars:variables];
    NSLog(@"postMeFeedButtonPressed:  %@", fb_graph_response.htmlResponse);


    //parse our json
    SBJSON *parser = [[SBJSON alloc] init];
    NSDictionary *facebook_response = [parser objectWithString:fb_graph_response.htmlResponse error:nil];   
    [parser release];

    //let's save the 'id' Facebook gives us so we can delete it if the user presses the 'delete /me/feed button'
    self.feedPostId = (NSString *)[facebook_response objectForKey:@"id"];
    NSLog(@"feedPostId, %@", feedPostId);
    NSLog(@"Now log into Facebook and look at your profile...");

}

这将在嵌入式播放器中显示音频内容。 希望这对某人有帮助。

谢谢

您好，我已经使用了此代码，但嵌入式播放器无法工作。我的音频文件URL是。它在facebook上的表现是这样的
