ios - 如何使用 Swift 从 Parse 中的 _User 类获取 currentUserInfo

Question

我尝试过这个:

var data:NSMutableArray = NSMutableArray()

func loadData() {
    var userQuery = PFUser.query()!
    userQuery.whereKey("objectId", equalTo: PFUser.currentUser()!.objectId!)
    userQuery.findObjectsInBackgroundWithBlock { (objects, error) -> Void in
       if let objects = objects {
          for object in objects  {
              self.data.addObject(object)
          }
       }
    }
    println(data) // this gives an empty NSMutableArray.
}

还有其他方法可以获取当前用户的数据吗？ ，我这样做是为了制作当前用户的个人资料屏幕..感谢您的时间..

使用它来访问当前用户

if PFUser.currentUser() != nil {
    PFUser.currentUser()!.fetchIfNeededInBackgroundWithBlock({ (user: PFObject?, error: NSError?) -> Void in
        if user != nil {
            var u = user as! PFUser
            //Access the fetched user HERE
         }
    })
    //NOT here, it will be nil here
}
