IOS播放音效

1.导入AVFoundation框架

import AVFoundation

2.获取音效对应的soundID

guard let url = NSBundle.mainBundle().URLForResource("123.wav", withExtension: nil) else{return}

let urlCF = url as CFURLRef

var soundID:SystemSoundID = 0;

AudioServicesCreateSystemSoundID(urlCF, &soundID)

3.根据soundID播放音效,带完成时回调

AudioServicesPlaySystemSoundWithCompletion(soundID) { 
            print("播放完成时回调")
            //根据soundID释放音效
            AudioServicesDisposeSystemSoundID(soundID)
        }
