so whats the best way to scale for the different aspect ratios on iphones when using cocoonjs? I read the tutorial on scaling for mobile devices but it seems that's not supported by cocoonjs which still seems the best bet for iphone publishing (please correct me if im wrong here)
Develop games in your browser. Powerful, performant & highly capable.
I'm not sure why it seems to you that scaling for mobiles like explained in the tutorial wouldn't work on the most used exporter for mobile.
The ways described should work.
