ios播放系統自帶音效以及震動

int systemsoundid；

audioservicesplaysystemsound(systemsoundid);

//systemsoundid的取值範圍在1000-2000

//播放自己的聲音，但此種播放方法主要播放一些較短的聲音檔案

nsstring *path = [nsstring stringwithformat:@"%@%@", [[nsbundle mainbundle] resourcepath], 

@"/jad0007a.wav"];

id systemsoundid soundid;

nsurl *filepath = [nsurl fileurlwithpath:path isdirectory:no];

audioservicescreatesystemsoundid((cfurlref)filepath, &soundid);

audioservicesplaysystemsound(soundid);

需求大緻分為三種：

1.震動

2.系統音效（無需提供音頻檔案）

3.自定義音效（需提供音頻檔案）

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為例

wqplaysound *sound = [[wqplaysound alloc]initforplayingsystemsoundeffectwith:@"tock" oftype:@"aiff"]; 

2.3自定義音效，将tap.aif音頻檔案加入到工程

wqplaysound *sound = [[wqplaysound alloc]initforplayingsoundeffectwith:@"tap.aif"];
