关于ios：为什么每次我的声音快速播放时我的游戏都会有延迟？

Why is there a lag in my game everytime my sound is being played in swift?

每次我点击屏幕时都会播放声音，但游戏中有轻微的打嗝，您可以看到它滞后于屏幕。我将如何解决这个问题？

class level1: SKScene, SKPhysicsContactDelegate, GKGameCenterControllerDelegate {

var jumpSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("tapsound", ofType:"wav")!)

var jumpAudioPlayer = AVAudioPlayer()

override func didMoveToView(view: SKView) {

jumpAudioPlayer = AVAudioPlayer(contentsOfURL: jumpSound, error: nil)
jumpAudioPlayer.prepareToPlay()

}

override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {

theHero.physicsBody?.applyImpulse(CGVector(dx: 0, dy: 200))
jumpAudioPlayer.play()

}

}

降低您播放的音频的质量/比特率。
