Question

任何人都可以帮助我插入我的highscoreLabel，我一直在生成错误，我已经看过将代码移动到viewDidAppear和viewDidLoad。

我刚刚开始使用swift，所以如果有人能提供帮助那就太棒了。

谢谢。

import UIKit
import SpriteKit
import AVFoundation
import GameKit

class StatsViewController: UIViewController {

var highScoreLabelNode = SKLabelNode()
var highScore = NSInteger()
var highscoreDefault = NSInteger()

    override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(true)

            let highscoreDefault = NSUserDefaults.standardUserDefaults()
    let score = highscoreDefault.valueForKey("HighScore")

    highScoreLabelNode.fontName = "Helvetica-Bold"
    highScoreLabelNode.position = CGPoint(x: 2.48, y: 1.17 )
    highScoreLabelNode.fontSize = 30
    highScoreLabelNode.alpha = 0.7
    highScoreLabelNode.text = "Highscore \(score)"

    addChild(highScoreLabelNode) //USE OF UNRESOLVED IDENTIFIER 'ADDCHILD'

}



override func viewDidLoad() {
    super.viewDidLoad()

        }

override func shouldAutorotate() -> Bool {
    return true
}

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
    if UIDevice.currentDevice().userInterfaceIdiom == .Phone {
        return UIInterfaceOrientationMask.AllButUpsideDown
    } else {
        return UIInterfaceOrientationMask.All
    }
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Release any cached data, images, etc that aren't in use.
}



override func prefersStatusBarHidden() -> Bool {
    return true
}
}

查看错误，您应该看到问题在于addChild不是函数，因此将其放在其他函数中将无法解决此问题。您需要在视图控制器的视图上调用正确的函数。

根据以下相关问题的答案，我认为您需要：

self.view.addSubview(highScoreLabelNode)
