Download progress event is not working in ios using cordova plugin file transfer

I am using cordova file transfer plugin to download files from my app.

But, when I m using progress event to show the user to progress bar on downloading It is not working properly every time it shows 0%.

Here is code which I used to show progress event....

$cordovaFileTransfer.download(url, targetPath, downloadOptions,
    trustHosts).then(function(result) {
}, function(err) {
}, function(progress) {
    if (progress.lengthComputable) {
        $rootScope.downloadProgress = (progress.loaded / progress.total) * 100;
    } else {
        $rootScope.downloadProgress = (progress.loaded / file_size) * 100;
    }
});

Can anyone please help me out to solve this downloading progress bar issue in ios.

function (progress) {
                    $timeout(function () {
                        $scope.downloadProgress = (progress.loaded / progress.total) * 100;
                        console.log($scope.downloadProgress)
                    });
                }

Replace your progress function with this function, u can check your result in console

I had the same problem six months ago, it seems to be a bug in the Filetransfer plugin.

The solution I found was to do the changes mentioned here: https://issues.apache.org/jira/browse/CB-9936

In CDVFileTransfer.m, download() method between line 447 to 462

delegate.connection = [[NSURLConnection alloc] initWithRequest:req delegate:delegate startImmediately:NO];

if (self.queue == nil) {
    self.queue = [[NSOperationQueue alloc] init];
}

[delegate.connection setDelegateQueue:self.queue];

@synchronized (activeTransfers) {
    activeTransfers[delegate.objectId] = delegate;
}

// Downloads can take time
// sending this to a new thread calling the download_async method
dispatch_async(
    dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, (unsigned long)NULL),
    ^(void) { [delegate.connection start];}
    );

If I replaced it with the older version of the code, then it works.

delegate.connection = [NSURLConnection connectionWithRequest:req delegate:delegate];
if (activeTransfers == nil) {
    activeTransfers = [[NSMutableDictionary alloc] init];
}
[activeTransfers setObject:delegate forKey:delegate.objectId];
