AVObject *todoFolder = [comment objectForKey:@"targetTodoFolder"];
AVUser *avUser = [todoFolder objectForKey:@"targetAVUser"];

这两句在swift中该怎么表达，我的代码时这样的

    query.findObjectsInBackground{ (results,error) in

        if  let results = results as? [AVObject]{

            self.creas = results

            OperationQueue.main.addOperation {

                self.refreshControl?.endRefreshing()

                self.tableView.reloadData()
            }

        }else{
            print(error ?? "123")
        }
    }

参考过文档了，不过，我的代码里。results 是一个数组，没办法使用 object(forKey: )
