barcodereader-monotouch's Issues

Does not work on iOS5beta6 / iPad2

Hi Goran,

thanks for your great work. Your work is appreciated very much.

We are using your library inside a project as a QR-code-reader and it works perfect (while not being as fast as red-laser ;-))

Today I updated my iPad2 to iOS 5 beta 6 (before it was a iOS 4.3-device).
On the iPad our application and your test-client do no longer work. The application comes to a stop after displaying the overlay.
The code seems to hang at:

            //The iris - we don't want that one
            NSNotificationCenter.DefaultCenter.AddObserver(new NSString("PLCameraViewIrisAnimationDidEndNotification"), (notification) => {   

                if(this.View != null)
                {
                    _imageView.RemoveFromSuperview();

                    this.OverlayView.StartWorker();
                }
            });  

If I disable the "iris"-code and simple remove to image and start the overlayview-worker, the camera image is shown, but a few times each second a "Exception of type 'com.google.zxing.ReaderException' was thrown." is thrown.
I did not find the source to this error.

We are still some time away from iOS 5 release, but it would be great, if you had a look into that issue.

Best greetings from Germany

Camera won't open

Hi,

If you press scan, cancel, home, and scan, the camera never opens. Please see this post on StackOverflow for more info:

http://stackoverflow.com/questions/11332855/monotouch-zxing-camera-wont-open

It appears when this app runs in the background, it fails to work. If the camera is closed and I press cancel and scan, the camera reopens. It appears running on a background thread is an issue.

LED light during scanning barcode/QR

Hi Goran,

Do you know an option for enabling the iPhones LED light during scanning?

Won't scan

Hi,

I am trying to make this work on an iPad 2 and iPad 3, both running iOS 5.1 and after the application fires up, it simply won't recognise the barcode, no matter how clear or close it is. Occasionally, it will crash the app.

I tried debugging the app to see if the BarCodeEvent fires but it doesn't.

Can you help?

Many thanks in advance
Joe
