我有一个简单的SKAudioNode:
let backgroundSound = SKAudioNode(fileNamed: "backgroundSound.mp3")
我用backgroundSound.runAction(SKAction.play())
和backgroundSound.runAction(SKAction.stop())
来停止。
一切正常,直到应用程序进入后台模式,我将恢复超过3分钟。 如果我进入后台模式并在10-20秒后恢复,则音频不会崩溃。
所有崩溃日志:

我还使用此通知暂停所有场景广告停止SKAudioNode操作:
func applicationDidEnterBackground(application: UIApplication) {
NSNotificationCenter.defaultCenter().postNotificationName(notificationPauseGame, object: nil)
}
你有什么想法吗?
谢谢你们
答案 0 :(得分:0)
您可以尝试使用以下命令加载文件:
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,而无需留下fileNamed
来搜索主捆绑,这是另一种选择。
