我希望能够按创建日期组织我从解析中收到的数据,我该怎么做?

我在线查看了解析文档,但我找不到任何说明如何按创建日期查询数据的内容。我也看到了堆栈溢出的答案,但它是在Objective-c中。请快速回答。

以下是我现在用于接收数据的代码......

  var query = PFQuery(className:"Class Name")
//this is what i tried..
        query.orderByDescending("createdAt")

//
        query.findObjectsInBackgroundWithBlock {
            (objects: [AnyObject]?, error: NSError?) -> Void in

            if error == nil {
                // The find succeeded.
                // Do something with the found objects


                if let objects = objects as? [PFObject] {
                    for object in objects {

                        self.NameArray.insert(object.valueForKey("Name")! as! String, atIndex: 0)
                        self.TextArray.insert(object.valueForKey("Text")! as! String, atIndex: 0)






                    }
                }
            } else {
                // Log details of the failure
                self.alert("Error: \(error!.localizedDescription)", Message: "Make sure you have a secure internet connection")
            }

            dispatch_async(dispatch_get_main_queue()) {

                println("Finished importing")

            self.collectionView.reloadData()


            }
        }
