如何將字符串轉換爲PFObject

Question

我已將用戶標識保存在解析列中作爲String，我想將它轉換爲PFObject。我該如何迅速做到這一點？我試圖獲取用戶id如下：

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

      if let objects = objects { 

       for object in objects { 

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

，我收到此錯誤：

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

感謝您的時間。

試試這個

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"] 
      } 
}
