I have designed my UI for 1536x2048 resolution maximum (iPad Air), but I want to view my UI on iPhone 4S too (640x960) or in any smartphone. So, I choose "fixed size on mobiles" like scaling style setting manual height to 2048 (my target height).
I have designed a piano takes all width in my design (1536 pixels) and I want to it fills all width of any device. In game view, if I set 1536x2048 resolution there is no problem, I view all piano keys but if I set to other resolution, for example iPhone 4S resolution, I do not view all piano keys.
I thought if I choose "fixed size on mobiles" this would scale proportionally all my widgets to view them like in the designed UI resolution. Only, if I change the orthographic size of UICamera I view always all the piano keys.
Any suggestion?
