iOS开发——播放系统音效、自定义音效需求大致分为三种：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：[cpp] view plaincopyprint?// // WQPlaySound.h // WQSound // // Created by 念茜 on 12-7-20. // Copyright (c) 2012年 __MyCompanyName__. All rights reserved. // #import#import@interface WQPlaySound : NSObject

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
[cpp] view plaincopyprint?
WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingVibrate];
[sound play];
2.2系统音效，以Tock为例
[cpp] view plaincopyprint?
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
[cpp] view plaincopyprint?
WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingSoundEffectWith:@"tap.aif"]
