tystol / monotouch.zbar Goto Github PK

Hello mate,

First of all, thanks for sharing your job with us.

I would want to ask you if this binding is useful to the 1.3.1 version, simply changing the library .a in the project.

I need the dll library for iOS7.

Thanks a lot in advance!

Hello,

I have successfully integrated MonoTouch.ZBar, but there seems to be a memory leak.

When dismissing the the picker in "FinishedPickingMedia" in my ZBarReaderDelegate, the destructor of the reader is never called (neither is Dispose).

I subclassed ZBarReaderViewController so I can check destruction.

Is there a leak?

Thanks

Hello, I'm currently using this binding in a Xamarin.iOS app I'm building but I'm consistently running into an issue. Although this repo isn't very active, hopefully you could maybe shed some insight.

I've written a detailed post on the Xamarin forums, but I'll copy what I've written for convenience: http://forums.xamarin.com/discussion/6773/app-crash-when-opening-zbar-barcode-scanning-view-controller#latest

When it wants to work, everything works great. The scanning is very accurate and quick, and it would really be a shame if I had to switch libraries.

Unfortunately, I'm running into a really weird issue with it. It starts off with me compiling the binding project and referencing the .dll in my real application. The library contains a child class of UIViewController, called ZBarReaderViewController. This view controller activates the camera and displays what it sees, and (from what I assume) periodically takes snapshots and analyzes them for valid barcodes.

In my app, I have a button in my navigation bar which instantiates my own child class of ZBarReaderViewController in order for the user to start scanning. This is where I run into my issue. After a seemingly random amount of time, or number of app launches, all of a sudden when I click the camera button, the app instantly crashes. This happens again and again, consecutively, until I either rebuild both the binding project and my app (which doesn't always work), or reboot the device (which also doesn't always work).

No exception is thrown either, so there isn't anything useful in Xamarin Studio while debugging, and often times the program itself will crash or otherwise experience issues after the app on the phone does. All I have to go by is the Xcode console output during the crash, which you can see here: http://pastebin.com/raw.php?i=x11YHYpu

Unfortunately I'm still a newbie at deciphering these iOS errors, so I'm not even sure where to look at this point. If anyone has any suggestions or things to try to at least narrow down the cause of the issue, I would be very grateful.

Is there any documentation or sample code on the usage of this. We are looking into using ZBar in our Xamarin.iOS application.

EDITED: Nevemind, I am an idiot.

Hi Team,

Is ZBar binding supports ARMV7s architecture?

I am getting this warning when I build my project with "Release" mode.

Warning MT1301: Native library libzbar.a (i386, armv6, armv7) was ignored since it does not match the current build architectures (armv7, armv7s) (MT1301)

Does it have any issue when users scans with iPhone 5 or iPhone 5s or 5c etc.,

Thank you in advance for your valuable reply.

I'm trying to integrate this into an existing Xamarin.iOS application that I have. I literally copied and pasted the code from the sample into my project(a few changes because it's in an UITableViewSource instead of a UIViewController), added reference for Zbar.dll, and added the 'libzbar.a' to the project. When running in debug on an iPod Touch running iOS 5.1.1, I get the following error message...

Wrapper type 'ZBar.ZBarReaderViewController' is missing its native ObjectiveC class 'ZBarReaderViewController'.

It happens on this line of code...

var barcodeReader = new ZBarReaderViewController();

I forked the current 'master' branch and built it. Not really sure where to start on this.
