"cordova-plugin-media" 2.4.0 will shut down immediately in iOS when use "getCurrentPosition" method

I test many times，these are all my code，just use it directly

=====
function recordAudio() {
if (navigator.userAgent.match(/iPad|iPhone|iPod/i))

{ var extension = ".wav"; }

if (navigator.userAgent.match(/Android/i))

{ var extension = ".amr"; }

var src = 'myrecording' + extension;
var mediaRec = new Media(src, function()

{ alert("recordAudio():Audio Success"); }

, function(err)

{ alert("recordAudio():Audio Error: " + err.code); }

);
mediaRec.startRecord();
setTimeout(function()

{ mediaRec.stopRecord(); alert('stop record'); }

, 3000);

setTimeout(function() {
mediaRec.getCurrentPosition(function(position) {
if (position > -1)

{ alert(position + " sec"); }

},
function(e)

{ alert("Error getting pos=" + e); }

);
}, 5000);
}
