使iPhone振动:AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)未声明

Question

我想让iPhone震动,我找到了代码

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

但Xcode 4.3.2报告错误:未声明的标识符kSystemSoundID_Vibrate

有什么问题？

Answer 1

尝试:

AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);

编辑:还要确保您导入AudioToolbox.framework

• #import <AudioToolbox/AudioToolbox.h>
