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
1
WQPlaySound
*sound=[[WQPlaySoundalloc]initForPlayingVibrate];
2
[sound
play];
2.2系统音效，以Tock为例
1
WQPlaySound
*sound=[[WQPlaySoundalloc]initForPlayingSystemSoundEffectWith:@
"Tock"
ofType:@
"aiff"
];
2
[sound
play];
2.3自定义音效，将tap.aif音频文件加入到工程
1
WQPlaySound
*sound=[[WQPlaySoundalloc]initForPlayingSoundEffectWith:@
"tap.aif"
];
2
[sound
play];
