ios - 如何将字符串转换为 PFObject

Question

我已将 userIds 保存在解析为 String 的列中，并且我想将其转换为 PFObject 。我怎样才能快速做到这一点？我试图按如下方式检索 userId:

followedUserQuery.findObjectsInBackgroundWithBlock { (objects, error) -> Void in

            if let objects = objects {

                for object in objects {

                    var followedUser = object["user"] as! PFObject

我收到此错误:

Could not cast value of type '__NSCFString' (0x105f94c50) to 'PFObject' (0x104708998).

感谢您的宝贵时间。

试试这个

followedUserQuery.findObjectsInBackgroundWithBlock { (objects:[AnyObject], error:NSError) -> Void in
          if error == nil{
     if let objects = objects as! [PFObject] {
                for object in objects {
             var followedUser = object["user"] 
            }
}
