iOS开发 - 播放系统音效、自定义音效

播放系统音效、自定义音效工具类


需求大致分为三种：
1.震动
2.系统音效（无需提供音频文件）
3.自定义音效（需提供音频文件）


我的工具类的封装：

调用方法步骤：
1.加入AudioToolbox.framework到工程中
2.调用WQPlaySound工具类

2.1震动

        WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingVibrate];          [sound play];

2.2系统音效，以Tock为例

    WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingSystemSoundEffectWith:@"Tock" ofType:@"aiff"];      [sound play];

2.3自定义音效，将tap.aif音频文件加入到工程

    WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingSoundEffectWith:@"tap.aif"];      [sound play];
