Parse.com 查询用户类 (swift)

问题描述

当我尝试从User"类中查询所有用户时遇到一些奇怪的问题它没有找到任何用户

I encounter some strange problem when I try to query all users from the "User" class It dos not find any Users

var query:PFQuery=PFQuery(className: "User");
    query.findObjectsInBackgroundWithBlock {
        (objects: [AnyObject]!, error: NSError!) -> Void in
        if !(error != nil) {
            for(var i=0;i<objects.count;i++){
                var object=objects[i] as PFObject;
                var name = object.objectForKey("username") as String;
                println(name);

            }
        }
    }

我尝试更换

 var query:PFQuery=PFQuery(className: "User");

与

var query:PFQuery=PFQuery(className: "AnotherClass");

一切都像我应该的那样工作.我认为用户"类一定有什么特别之处

and everything worked like i should. I think it must be something special about the "User" class

推荐答案

User 不是 User 表的适当名称.您需要使用以下内容:

User isn't the appropriate name for the User table. You need to use the following:

var query : PFQuery = PFQuery(className: "_User")

更合适的方法是:

var query : PFQuery = PFUser.query()
