Long Pause When Initiating Scanner

[dpotts]

The time between initiating the scanner and the camera fully loaded up seems to be a lot longer (a few seconds) than that of the camera app and other QR scanner apps. I am running it on iOS7. Here is code i am using:

        var scanner = new MobileBarcodeScanner();

        var options = new MobileBarcodeScanningOptions()
        {
            PossibleFormats = new List<BarcodeFormat>() { BarcodeFormat.QR_CODE },
        };
        options.AutoRotate = false;
        options.TryHarder = false;

        scanner.UseCustomOverlay = false;
        scanner.Scan().ContinueWith((t) => { ShowMessage(t.Result != null ? t.Result.Text : "Canceled / No QR Code"); });

Any idea why the long pause?

Can you quantify the length of the pause? It certainly takes a few seconds for me, but it's not really that slow on the 4S with iOS7

On iPad Mini it take 2-3 seconds to load. Is this expected?

Takes ~2 seconds on my iPhone 4S... So that seems about right.

If you're interested in trying to squeeze some extra speed out of it, by all means, please send a pull request :)

For repeated launches, #71 might help address startup speed...

Closing this issue for now, if you find any specific areas for concern please reopen, otherwise, i think it's just how long it takes to do this in managed code :s
