Is there a notification that I can listen to that will tell me when an iPhone’s volume up or down button is pressed ?

If you are doing a native app, yes, you can listen for the volumedownbutton or volumeupbutton events to be fired:

Thanks for the tip. I tried it. But no luck. I added the code. Do i miss something. the event ‘deviceready’ is fired, but the event ‘volumedownbutton’ does not.

phoneui.documentReadyHandler = function() {
alert('load');
}
    
  var pictureSource;   // picture source
  var destinationType; // sets the format of returned value 

    // Wait for Cordova to connect with the device
    //
    document.addEventListener("deviceready",onDeviceReady,false);
    
    // Cordova is ready to be used!
    //
     function onDeviceReady() {
        pictureSource=navigator.camera.PictureSourceType;
        destinationType=navigator.camera.DestinationType;
       document.addEventListener("volumedownbutton", onVolumeDownKeyDown, false);
      alert('onDeviceReady');
    }
    
   function onVolumeDownKeyDown() {
     alert('VolumeDownKeyDown');
    }

Try checking the Debugger to make sure there are no errors anywhere else in the script.
Also, if you are building for Android make sure you set any permissions it may need, iOS doesnt have any to set.

Thank you for your reply,

I was too fast and didn’t read the instruction that well, PhoneCap doesn’t support this event for iOS.

I’m trying to make an application, to operate my lights, blinds by my iPhone and iPad. I wanted to use the volume buttons to dim the lights .

Is there a another way?
