我的 SKAudioNode 有问题。游戏以 Home 键结束。将播放一个音频文件。

当我返回时，音频文件将继续播放。

我想阻止它。

我尝试了很多事情，但没有成功。

self.AudioNodeSet.removeFromParent()// 不起作用

self.AudioNodeSet.run(SKAction.stop())// 也不起作用

谁能帮我？

class GameScene: SKScene {  
 var AudioNodeSet = SKAudioNode()  
     override func didMove(to view: SKView) {  
     self.addChild(AudioNodeSet) // Audio Node  
        AudioNodeSet.name = "AudioNodeSet"  
......  

func applicationWillResignActive(_ application: UIApplication) {  
        let imageView = UIImageView(frame: self.window!.bounds)  
        imageView.tag = 101  
        imageView.backgroundColor = UIColor.white  
        //imageView.contentMode = .center  
        imageView.contentMode = .scaleAspectFill  
        let pic = UIImage(named: "Start Page.jpg") // Overwrite Return Scene  
        imageView.image = pic  
        UIApplication.shared.keyWindow?.subviews.last?.addSubview(imageView)  
    }  

........  

override func didMove(to view: SKView) {  

        scene?.size = CGSize(width: 1920, height: 1080)  
        scene?.backgroundColor = .black   
        scene?.scaleMode = .aspectFill   

        let notificationCenter = NotificationCenter.default  
        notificationCenter.addObserver(self, selector: #selector(appMovedToBackground), name: UIApplication.willResignActiveNotification, object: nil)  
        notificationCenter.addObserver(self, selector: #selector(appMovedToForeground), name: UIApplication.didBecomeActiveNotification, object: nil)  
        notificationCenter.addObserver(self, selector: #selector(appWillTerminate), name: UIApplication.willTerminateNotification, object: nil)  

.........  

@objc func appMovedToForeground() {  

        print("applicationWillResignActive -> appMovedToForeground")  
        self.AudioNodeSet.run(SKAction.stop()) // not work!  
        self.AudioNodeSet.removeFromParent() // second try -> not work!

此代码在游戏继续时执行。

然后可以听到音频文件的其余部分。
