播放代码:

  -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
  {
    //1.获得音效文件的全路径

    NSURL *url=[[NSBundle mainBundle]URLForResource:@"buyao.wav" withExtension:nil];

    //2.加载音效文件,创建音效ID(SoundID,一个ID对应一个音效文件)
    SystemSoundID soundID=0;
    AudioServicesCreateSystemSoundID((__bridge CFURLRef)url, &soundID);

    //把需要销毁的音效文件的ID传递给它既可销毁
    //AudioServicesDisposeSystemSoundID(soundID);

    //3.播放音效文件
    //下面的两个函数都可以用来播放音效文件,第一个函数伴随有震动效果
    AudioServicesPlayAlertSound(soundID);
    //AudioServicesPlaySystemSound(<#SystemSoundID inSystemSoundID#>)
