SKAudioNode崩溃:AVAudioPlayerNode.mm:333:开始:所需条件为假:_engine-> IsRunning() [英] SKAudioNode Crash: AVAudioPlayerNode.mm:333: Start: required condition is false: _engine->IsRunning()

问题描述

我有一个简单的SKAudioNode:

I've a simple SKAudioNode:

let backgroundSound = SKAudioNode(fileNamed: "backgroundSound.mp3")

我曾经玩backgroundSound.runAction(SKAction.play())，而backgroundSound.runAction(SKAction.stop())停了.

一切正常，直到应用程序确实进入了后台模式，我将继续3分钟以上. 如果我进入后台模式并在10到20秒后恢复播放，则音频不会崩溃.

Everything works fine until the app did enter in background mode and I'll resume more than 3 minute. If I go in background mode and resume after 10 - 20 seconds, the Audio doesn't crash.

所有崩溃日志:

libc++abi.dylib: terminating with uncaught exception of type NSException

我还使用此通知来暂停所有场景广告停止SKAudioNode操作:

I use also this notification to pause all scene ad stop SKAudioNode action:

func applicationDidEnterBackground(application: UIApplication) {
        NSNotificationCenter.defaultCenter().postNotificationName(notificationPauseGame, object: nil)
    }

你有什么主意吗?

谢谢大家

推荐答案

您可以尝试通过以下方式加载文件:

You could try to load your file with:

var backgroundMusic: SKAudioNode!

if let musicURL = NSBundle.mainBundle().URLForResource("backgroundSound", withExtension: "mp3") {
    backgroundMusic = SKAudioNode(URL: musicURL)
    addChild(backgroundMusic)
}

此方法直接提供您的音频资源，而无需留给fileNamed在主捆绑中进行搜索，这是另一种选择.

This method give directly your audio resource without leave to fileNamed to search in main bundle , it's an alternative.
