import UIKit
import Parse

class ViewController: UIViewController {

    var Question: String!
    var Answers: [String]!
    var Answer: String!

    @IBOutlet weak var QuestionLabel: UILabel!

    @IBOutlet weak var Button1: UIButton!

    @IBOutlet weak var Button2: UIButton!

    @IBOutlet weak var Button3: UIButton!

    @IBOutlet weak var Button4: UIButton!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        CallData()

    }



    func CallData(){

        var query : PFQuery = PFQuery(className: "QuestionsandAnswers")
        query.getObjectInBackgroundWithId("Mo4HYEB8EC"){
            (ObjectHolder : PFObject!, error : NSError!) -> Void in

            if (error == nil){

                self.Question = ObjectHolder["Question"] as String!
                self.Answers = ObjectHolder["Answers"] as Array!
                self.Answer = ObjectHolder["Answer"] as String!

                if (self.Answers.count > 0){
                    self.QuestionLabel.text = self.Question

                    self.Button1.setTitle(self.Answers[0], forState : UIControlState.Normal)
                    self.Button2.setTitle(self.Answers[1], forState : UIControlState.Normal)
                    self.Button3.setTitle(self.Answers[2], forState : UIControlState.Normal)
                    self.Button4.setTitle(self.Answers[3], forState : UIControlState.Normal)


                }


            }
            else{

                NSLog("Error. Wrong!")

            }

        }
    }


    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func Button1Action(sender: AnyObject) {
    }
    @IBAction func Button2Action(sender: AnyObject) {
    }
    @IBAction func Button3Action(sender: AnyObject) {
    }
    @IBAction func Button4Action(sender: AnyObject) {
    }
}

这就是我的全部代码。我的 Parse.com 组织为 objectId、createdAt、updatedAt、ACL、Questions（字符串）、Answers（字符串数组）、Answer（字符串，但其值为数字。）

我知道我肯定遗漏了一些东西，否则它会起作用，但我只是在调试它时遇到了麻烦。

我遇到了同样的问题。这个花了半天时间。我做了两个更改。

检查 Parse 并确保您的 Answer 列被命名为 "Answer"。我的名字叫 "Array"，这把我搞砸了。
我修改了选项及其感叹号和问号。请参阅下面的代码。
```
    (ObjectHolder : PFObject?, error : NSError?) -> Void in
```
如果（错误==无）{ self.Question = ObjectHolder?["Question"] 为！细绳 self.Answers = ObjectHolder?["Answers"] 为！大批 self.Answer = ObjectHolder?["Answer"] 为！字符串
