推荐答案

SKAction 非常容易使用声音，但有时你可能想要做更多。

SKAction is really easy to use with sounds, but sometimes you might want to do more.

在这种情况下，你会想要使用 AVAudioPlayer 代替它。

In that case, you would want to use AVAudioPlayerinstead of it.

为了不写自己的播放器，我建议你使用现有的。这是我已经使用的（SKTAudio）： https：// github .com / raywenderlich / SKTUtils / blob / master / SKTUtils / SKTAudio.swift

In order to not write your own "player", I suggest you to use an existing one. Here is one I've already used (SKTAudio) : https://github.com/raywenderlich/SKTUtils/blob/master/SKTUtils/SKTAudio.swift

以下是如何使用它：

// For background audio (playing continuously)
SKTAudio.sharedInstance().playBackgroundMusic("yourBackgroundMusic.mp3") // Start the music
SKTAudio.sharedInstance().pauseBackgroundMusic() // Pause the music
SKTAudio.sharedInstance().resumeBackgroundMusic() // Resume the music

// For short sounds
SKTAudio.sharedInstance().playSoundEffect("sound.wav") // Play the sound once

正如你所看到的，你可以播放短音（就像你可能已经用 SKAction 那样），甚至可以播放循环播放的背景音乐。正在寻找。

As you can see, you'll be able to either play short sound (as you might already have done with SKAction) and even background music that will play in loop as you're looking for.
