ofAppiPhoneWindow was missing in my app ... but everything were fine ...

Could someone help me with ofAppiPhoneWindow stuff ? (I mean method related)

I didn’t put that in my app, it worked, but …
should I have to use it in any case or not?

especially, that:
iOSWindow->enableRetinaSupport();

is it required to … support Retina or does XCode pack that when you put Universal as target ?
