Parse.com PFQuery 按时间排序(Swift)

问题描述

我试图根据最近创建的对象获取所有对象，但它总是从一开始就返回，我想要最新的，这是我的代码

I'm trying to get all the objects depeding on how recently they were created but its always returning from the start and i want latest first, here is my code

var query:PFQuery = PFQuery(className: "Notes")
query.orderByDescending("CreatedAt")
query.findObjectsInBackgroundWithBlock{ (objects,error) -> Void in
   if error == nil {
      for object in objects {
         self.array.addObject(object)
      }
   }
}

我尝试升序，但仍然返回相同的对象.

I tried ascending order but still returns same objects.

推荐答案

我认为问题只是 "createdAt" 字段以小写 'C' 开头，而不是大写，所以你应该试试:

I think the problem is just that "createdAt" field starts with a lowercase 'C', not an uppercase, so you should try:

query.orderByDescending("createdAt")
