angularjs - Cordova katzer plugin background mode not working on iOS-9 -

in ionic/angularjs application use https://github.com/katzer/cordova-plugin-background-mode/ backgrounding application.

it's working quiet on ios-8 new ios-9 not working more. did few tests , looks app working in background user gets no information it. on ios-8 message "yourapp using location" or on top of display. on ios-9 message missing.

did same experience plugin?

i found out there changes in core location functions on ios9: allowsbackgroundlocationupdates in cllocationmanager in ios9

like suggested in post add default property allowsbackgroundlocationupdates value yes org.apache.cordova.geolocation plugin.

with fix on cdvlocation.m located in /plugins/org.apache.cordova-geolocation/src/ios/ works.

to bring work removed platform ios cordova platform remove ios , added again cordova platform add ios builds plugins new.

now i'm getting blue bar on display again :-)

this fix break geolocation support on ios < 9.0. bring work older versions 9.0 use cdvlocation.m file:
