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：

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];
