I'm not even sure if that is causing my problem. I am trying to install https://github.com/EddyVerbruggen/Cal...
For iOS, I put Calendar.h and .m in /APP/CordovaLibPlugins/calendar and I put Calendar.js in /APP/Resources/www/project/files/resources/lib/plugins/calendar/www I edited cordova_plugins.js and config.xml. But it seems like the directory names should have the full nl.xservices.plugin.calendar name.
