import UIKit

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) {
    }
}

那是我的整个代码。我的Parse.com被组织为objectId，createdAt，updatedAt，ACL，Questions（字符串），Answers（字符串数组），Answer（字符串但其值是数字。）

我知道我肯定错过了一些东西，否则它会起作用，但我只是在调试它的时候很糟糕。

Answer 1

我遇到了同样的问题。在这个上花了半天时间。我做了两处修改。

检查解析并确保您的答案列已命名为＆＃34;答案＆＃34;。我被命名为＃34;阵列＆＃34;，这让我搞砸了。
我修改了选项及其感叹号和问号。请参阅下面的代码。
```
insert
```
if（error == nil）{ self.Question = ObjectHolder？[＆＃34; Question＆＃34;] as！串 self.Answers = ObjectHolder？[＆＃34;答案＆＃34;]为！排列 self.Answer = ObjectHolder？[＆＃34;答案＆＃34;]为！串
