--------------------------------
Summary: BarcodeScanner plugin on ios does not dismiss the scan
screen after user does not allow the permission
Key: CB-12781
URL: https://issues.apache.org/jira/browse/CB-12781
Project: Apache Cordova
Issue Type: Bug
Components: cordova-ios
Affects Versions: 1.5.0, Master
Environment: ios
Reporter: Jonathan Li
In ios cordova project with barcode scanner plugin, when first time running the
app, and call the below method
cordova.plugins.barcodeScanner.scan()
The app will show a dialog to ask user whether allow to use camera or not, if
user clicks "Do not allow" button, currently the permission dialog will
dismiss, but the scan screen is still opened, and as the app cannot use camera,
the user cannot do anything except for clicking the cancel button to cancel the
operation.
This is not a user-friend behavior, as when user clicks "Do not allow", the
user is already decided to cancel the operation, so the plugin should
automatically cancel the scan request, and dismiss the scan screen and also
return the cancel result to the cordova callback. There is no reason to still
leave the scan screen opened and have to require user to click the cancel
button to cancel the operation.
