Xcode9学习笔记63 - 使用SystemSoundId播放简短声音(太长的无法播放)

import UIKit
import AudioToolbox//导入音频工具箱框架，这样就可以使用系统声音服务了

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        
        var _soundId:SystemSoundID = 0//声明一个系统声音标识的声音变量
        let path = Bundle.main.path(forResource: "sheep", ofType: "mp3")//获取沙箱目录中，声音文件的所在路径
        let soundUrl = URL(fileURLWithPath: path!)//将字符串路径转换成网址路径
        //对于按键音、下拉菜单音等较短暂的声音，以及震动效果，可以使用系统音频服务来播放
        AudioServicesCreateSystemSoundID(soundUrl as CFURL, &_soundId)
        AudioServicesPlaySystemSound(_soundId)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
