AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)

Question

I'm working on a Custom Alarm App and want to use Vibration in my App as soon as the alarm plays and I have used AudioToolbox and used this below code:

AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))

and it worked but i want to run continuously vibration in my App.

is there any possible way to implement this??

you can use NSTimer and call your function which contain vibration code and when you want to stop it you can call NSTimer's release method.

Example code :

    NSTimer *t = [NSTimer scheduledTimerWithTimeInterval: 2.0
                                                  target: self
                                                selector:@selector(onTick:)
                                                userInfo: nil repeats:NO];

    -(void)onTick:(id)sender{

        AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))

    }

This code will vibrate device continuously with delay of 2 seconds. when you want to stop vibration you can call release method.

Ex. [t release];

You will have to repeat your vibration request.

NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval: 1.0 target: self selector:@selector(repeat:) userInfo: nil repeats:NO];

-(void)repeat:(id)sender{

  AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))

}

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)
