Does not work on iOS5beta6 / iPad2

stroendle commented 13 years ago

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

Update: I have downgraded my iPad2 to iOS 4.3.5.

The iris-problem is gone, so this seems to be definitely an iOS 5 issue.

But the exception com.google.zxing.ReaderException persists, so I cannot scan any barcodes on the iPad2, independent of the iOS-Version.

Hello I'm glad that you guys are using it. I will take look and try to fix it for IOS 5. I will let you know when it's fixed. Br Göran

Hello

I have not upgraded it for IOS5... But the error com.google.zxing.ReaderException, it occurs at BarcodeReader-MonoTouch / BarcodeTesting / Controllers / CameraOverLayView.cs in row 200. And it's suppose to do that. I have not tested it on iPad2.

Thanks for all this great work. I've used your example to add scanning to my app. But it only works on an iPhone, not my iPad 2. Any thoughts on getting the iPad to see a bar code?

Thanks, Rick

GoranHalvarsson commented 13 years ago

Hello

I will take a look on this iPad2 issue, as soon as I have an iPad2.

ric3kg commented 13 years ago

It looks like the problem is the device - there does not seem to be support for non-auto focus cameras. The iPad 2 and iPod Touch are both non-auto focus, so there does not seem to be a work around. But, if you figure one out, I'd love to hear about it!

Hi,

the problem for custom overlay is that the notification "PLCameraViewIrisAnimationDidEndNotification" is no longer used on iOS 5.

I didn't managed to find any replacement for this, for now at least I'm not showing the custom overlay, and I'm showing the default Iris. @GoranHalvarsson, unless you want I'm not submitting a patch for this since my solution is mostly to delete code ;) But if you want it please let me know.

GoranHalvarsson commented 13 years ago

Hello

Tank you for clearing it out. Yes I agree, no patch. Lets wait until we find a solution how to hide the iris in iOS 5. I'm glad that you are using it. :-)

Hi there,

I think I have found the problem which is preventing the software to run on an iPad2. It is, in my opinion, a bug of MonoTouch. I have filed it at http://bugzilla.xamarin.com/show_bug.cgi?id=1894

Best,

Stefan

Hello

I hope that they will fix the bug.
