Swift-AVAudioPlayer不起作用

Question

我試圖通過以下方式在iOS應用程序中播放aiff文件：

var sound = NSBundle.mainBundle().pathForResource("tropical_birds", ofType: "aiff")
var soundData = NSData(contentsOfFile: sound!)
let audioPlayer = AVAudioPlayer(data: soundData, error: nil)
audioPlayer.prepareToPlay()
audioPlayer.play()

Answer 1

您的AVAudioPlayer超出范圍並被釋放。 將其分配給您的類的實例變量以延長其壽命。

例如

self.audioPlayer = AVAudioPlayer(data: soundData, error: nil)
self.audioPlayer.prepareToPlay()
self.audioPlayer.play()
