phonegap-plugin-barcodescanner freeze on ios - ios

Question

I'm using ionic version 1.7.12 with the plugin phonegap-plugin-barcodescanner version 4.1.0 on OSX 10.11.2, additional node version is v0.10.26 and cordova 5.4.1 testing on IOS 6+, after my projects compile and install the ipa on the testing device when i try to open the scanner it freeze the app, something to add this is a legacy app.
The estrange thing its that if i start a new project from scratch using ionic cli and and install the plugin it works just fine.
Any place where i should look or what im doing wrong.
Thanks

What do you mean by "freeze"? i have similar problem, when i toggle bar code scanner with a button clicked, it open up a camera view and freeze, and by "freeze" i mean a image toked by the camera and not moving(you can still click cancel button and return back to the view).
i found out the button click event has toggle twice with one click and it explained why you have a image not moving.
i solved this problem by working around.
$scope.scannerActive = false;
$scope.scanBarcode = function() {
if(!$scope.scannerActive) {
$scope.scannerActive = true;
$ionicPlatform.ready(function() {
$cordovaBarcodeScanner.scan().then(
function(result) {
if (!result.cancelled) {
console.log(result)
}
else {
console.log('cancelled')
}
},function(error) {
alert(JSON.stringify(error));
}).finally(function() {
$scope.scannerActive = false;
});
});
}
};
