Icons and Splashscreens: ionic resources for platform that is not added

I have a question regarding the ionic function to create icon and splashscreen (ionic resources): I am developing on a windows machine and use phonegap build to build the ios version.

Using windows I can only add android as a platform. How do I create icons and splashscreens for ios without having it added as a platform? So far only icons for the added platforms are created.
Thank you in advance!

Did you solve it somehow? Thx

Yes, you just have to create an ios (android, winphone, etc.) folder under platforms directory and run the tool. Works with 1.0.0-beta.13.
