Hi,
it seems your are working with Xamarin or Cordova module.
In both cases you can modify all code with xCode and customize the Obj-C classes to include into your Xamarin/Cordova project.
For Xamarin, you can find the full code in RadaeeLib folder and the "make" file to create your customized library to include into your Xamarin project.
For Cordova, the plugin contains the full code and you can modify it freely.
