Question

我的问题是我的应用程序在暂停音频后崩溃。

Thread 1: EXC_BAD_ACCESS (code=1, address=0x48)

声音播放如下：

var audioPlayer = AVAudioPlayer()
var jumpAudio: URL?
var coinAudio: URL?
...

duck.run(SKAction.playSoundFileNamed("coin", waitForCompletion: true))

我通过在GameScene中调用此函数来暂停另一个类中的声音：

func setAudioOn(pOn: Bool) {

    if pOn == true {
        audioPlayer.play()
    }
    else if pOn == false {
        audioPlayer.pause()
    }
}

提前谢谢
