Facebook图形api发布评论等

Question

我在我的应用中使用Facebook图形api。我能够在UItableview中获得个人资料帖子列表。我调用了GetMeFeed（）方法并将数组传递给下一个类，如

FaceBookTable *detailViewController = [[FaceBookTable alloc] initWithNibName:@"FaceBookTable" bundle:nil];
    // ...
    // Pass the selected object to the new view controller.
    detailViewController.dummyArray  =  friendsArray;
    detailViewController.nameArray = nameArray;
    [self.navigationController pushViewController:detailViewController animated:YES];
    [detailViewController release];

在FacebookTable类中，我使用

显示帖子消息和id

cell.textLabel.text  = [dict objectForKey:@"id"];

//cell.textLabel.text = [dict objectForKey:@"name"]  ;
cell.detailTextLabel.text = [dummyArray objectAtIndex:indexPath.row];

现在我想评论任何帖子......我怎么能这样做..我知道网址......

但如何从facebooktable类提出请求
