我一直在遵循文档的指示：https://developers.facebook.com/docs/ios/share#message-dialog-getting-started
这就是我尝试过的：

[FBDialogs presentMessageDialogWithLink:[NSURL URLWithString:@"http://XXX.net/"] name:@"NAME" caption:@"CAPTION" description:@"DESCRIPTION" picture:nil clientState:nil handler:^(FBAppCall *call,NSDictionary *results,NSError *error) {
            if(error) {
                // An error occurred,we need to handle the error
                // See: https://developers.facebook.com/docs/ios/errors
                NSLog([NSString stringWithFormat:@"Error messaging link: %@",error.des

cription]);
        } else {
            // Success
            NSLog(@"result %@",results);
        }
    }];

而这:(应该是同一件事)

FBLinkShareParams *params = [[FBLinkShareParams alloc] init];
    params.link = [NSURL URLWithString:@"http://xxx.net/"];
    params.name = @"NAME";
    params.caption = @"CAPTION";
    //params.picture = [NSURL URLWithString:@"http://upload.wikimedia.org/wikipedia/en/c/cd/Aller_Media_logo.png"];
    params.linkDescription = @"DESCRIPTION";

    [FBDialogs presentMessageDialogWithParams:params clientState:nil
                                    handler:^(FBAppCall *call,NSError *error) {
                                        if(error) {
                                            // An error occurred,we need to handle the error
                                            // See: https://developers.facebook.com/docs/ios/errors
                                            NSLog([NSString stringWithFormat:@"Error messaging link: %@",error.description]);
                                        } else {
                                            // Success
                                            NSLog(@"result %@",results);
                                        }
                                    }];

这两种方法都会在我的Facebook Messenger应用程序中显示预先填充了我的参数的对话框.但是当我发送消息时,除了链接之外的所有内容都是GONE在接收方端.

根据我的理解,用户不必通过应用程序登录,以便能够从Facebook消息对话框发送消息.

有没有人知道这里发生了什么？这是一个Facebook Bug吗？
