Get an iPhone for Vibration

Question

I am trying to make iPhone vibrate with this code:

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

But it doesn’t work, maybe because I play the sound at the same time as the call?

Answer 1

This should work fine. Is vibration on the device turned off?

Answer 2

If this helps someone, I found that the vibrate command would not work while AVAudioRecorderit was recording. Getting around this is very simple. You just need to first stop your recorder and resume it:

[recorder stop];
AudioServicesPlaySystemSound (kSystemSoundID_Vibrate);
[recorder record];

It even works if you want to record sound and vibrate in the background with UIBackgroundModes.

Answer 4

On all the iPhones I tested (original, 3GS and 4), it should vibrate. On iPod touch 1st generation, it will play a sound through the built-in speaker. On iPod touch second generation, he will not do anything. He will not do anything on the iPad either. These are all the devices on which I tested.
