需求大致分為三種：
1.震動
2.系統音效（無需提供音頻文件）
3.自定義音效（需提供音頻文件）
我的工具類的封裝：

調用方法步驟：
1.加入AudioToolbox.framework到工程中
2.調用WQPlaySound工具類

2.1震動

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

2.2系統音效，以Tock為例

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

2.3自定義音效，將tap.aif音頻文件加入到工程

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