ios – 如何获取最近添加的parse.com对象

PFQuery *query = [PFQuery queryWithClassName:@"YourClassName"];
[query orderByDescending:@"createdAt"];
[query getFirstObjecTinBACkgroundWithBlock:^(PFObject *object,NSError *error) {
    // code
}];

在斯威夫特：

var query = PFQuery(className: "YourClassName")
query.orderByDescending("createdAt")
query.getFirstObjecTinBACkgroundWithBlock {(object: PFObject?,error: NSError?) -> Void in
    // code
}
