Play local audio files in ios cordova - ios

Question

I am using media plugin to play local audio files (inside /www folder). This perfectly works in android but in iOS the error "Cannot play the audio file from resource…." is coming.
Please check the below screenshot and coding. How should i solve this to play local audio files.
<script type="text/javascript">
function getPhoneGapPath() {
'use strict';
var path = window.location.pathname;
var phoneGapPath = path.substring(0, path.lastIndexOf('/') + 1);
return phoneGapPath;
};
// Audio player
var my_media = null;
var mediaTimer = null;
// Play audio
function playAudio() {
if (my_media == null) {
// Create Media object from src
my_media = new Media(getPhoneGapPath() +'button-click.wav', onSuccess, onError);
} // else play current audio
// Play audio
my_media.play();
}
// Pause audio
//
if (my_media) {
my_media.pause();
}
}
// Stop audio
function stopAudio() {
if (my_media) {
my_media.stop();
}
clearInterval(mediaTimer);
mediaTimer = null;
}
// onSuccess Callback
function onSuccess() {
console.log("playAudio():Audio Success");
}
// onError Callback
function onError(error) {
alert('code: ' + error.code + '\n' +
'message: ' + error.message + '\n');
}
</script>
