Systematic freeze on IOs #329

Open

lantenac commented May 19, 2016

Environment :
iphone :
phonegap-plugin-barcodescanner 5.0.0
ios : 9.3.2

Failure scenario :

I tap for launching the scan I bound on a button,
I re-tap the button before the scan get launched,
The scanner interface is displayed but frozen. I can exit though.

Remark : if i don't "double tap", scan is ok. It seems there is a concurrent access to the camera/video stream which is not properly handled.

Does anyone have a fix ?

Thanks a lot for your help.

Dorian.

Hi Dorian,

You can try all the lines that include "didAppear" which I made from a fork of the current cordova-plugin-barcodescanner repository that solved the same issue for me. https://github.com/ryanc35/cordova-barcodescanner-plugin/commit/1ca5684f812fbc149d8bc1b486882ecc36b8bef7

Regards,
Ryan
