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

1WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingVibrate];
2[sound play];

2.2系统音效，以Tock为例

1WQPlaySound *sound = [[WQPlaySound alloc]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

1WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingSoundEffectWith:@"tap.aif"];
2[sound play];
