在多个朋友的facebook墙上发帖

我只用一个Facebook墙贴进行申请.使用FBConnect对我来说很好.但是现在我想一次单击将墙贴一次发给多个朋友.是否可以在多个朋友的墙上发帖?如果可能的话，建议我.

I make application with only one facebook wall post. It works good for me using FBConnect. but now i want wall post to multiple friends at a time on one button click. Is it possible for post on multiple friends wall? If it is possible then suggest me.

我的代码:

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   [NSString stringWithFormat:@"%@",[[arrData objectAtIndex:i] objectForKey:@"id"]], @"to",
                                   @"post on facebook", @"name",
                                   @"facebook wall post", @"description",
                                   @"http://m.facebook.com/apps/myapp", @"link",
                                   nil];

    AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
    [[delegate facebook] dialog:@"feed"
                      andParams:params
                    andDelegate:self];

请回复我.

预先感谢您的帮助.
