Make iPhone vibrate: AudioServicesPlaySystemSound(kSystemSoundID_Vibrate) undeclared

Question

I want to make iPhone vibrate and I found the code

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

but Xcode 4.3.2 reports error: undeclared identifier kSystemSoundID_Vibrate

What's the problem?

Solution

Try:

AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);

EDIT: Also make sure you import AudioToolbox.framework

• #import <AudioToolbox/AudioToolbox.h>

Same error and there's no AudioServicesPlayAlertSound() method. Is it right to add AudioToolBox.framework?
