问题
I want to make an app where while the user is pushing down a button the phone vibrates until the user releases the button.
Ive searched around and I haven't found a way to make it a long vibrate, except for a very old tutorial from 2009 which seems to be outdated.
回答1:
It's not allowed by Apple to use the vibration as you want to:
Vibration. It is not permitted to use continuous vibration in your apps – short bursts as warnings is all that is allowed. Don’t bother trying to set up a timer to keep the vibration going, it will cause your app to be rejected.
It's not the method, but the result, that's not permitted.

Look on these options,
1) AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
2) AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

And, you need to import AudioToolBox framework,
#import <AudioToolbox/AudioServices.h>

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
repeat this line in between you start-stop vibrate. don't forgot to add and import
#import <AudioToolbox/AudioToolbox.h>
framework to your project.
