播放系統音效、自定義音效工具類
需求大致分爲三種:
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
- WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingVibrate];
- [sound play];
2.2系統音效,以Tock爲例
- 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
- WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingSoundEffectWith:@"tap.aif"];
- [sound play];
