问题描述
我正在尝试使所有对象都依赖于它们的创建时间,但是它总是从头开始返回,我想先获取最新信息,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"
字段以小写的'C'开头,而不是大写,因此您应该尝试:
I think the problem is just that "createdAt"
field starts with a lowercase 'C', not an uppercase, so you should try:
query.orderByDescending("createdAt")
