我有一個簡單的SKAudioNode:SKAudioNode崩潰:AVAudioPlayerNode.mm:333:啓動:需要的條件是假的:_engine-> IsRunning()

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

我用打backgroundSound.runAction(SKAction.play())backgroundSound.runAction(SKAction.stop())停止。

一切正常,直到應用程序確實進入後臺模式,我會恢復超過3分鐘。 如果我進入後臺模式並在10 - 20秒後恢復,則音頻不會崩潰。

所有的崩潰日誌:

我也用這個通知暫停所有廣告現場停止SKAudioNode行動:

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

你有什麼想法?

謝謝你們

你可以嘗試加載文件用:

var backgroundMusic: SKAudioNode! 

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

這一方法是直接給你的音頻資源不假,fileNamed在主束進行搜索,這是另一種選擇。
