Ashley thanks, this is really interesting.
So I could stretch the background based on the WindowHeight and Width properties myself and position all objects to the center of the screen and I would be done.
Still there is another small issue, on the iPad everytime you change layout with scale mode the layout starts in the center and then goes to the left side leaving a trail, you already told me about clear background (which also impacts performance as shown in another tutorial). If I set the unbounded scrolling what happens then?
To me it looks like this will happen:
c2 still has the aspect ratio of 1.5 (iPhone). The layout loads, the canvas get resized, only this time the background covers everything (I imagine this happens BEFORE any of my actions) then I reposition my objects and I would have a "simulation" of native resolution, is this right? But the ghosting will still happen without setting the clear background right? DId I got this right?
If this is the case this is really genious and you are one of the few frameworks that can support multiple aspect ratios out of the box!
If I'll ever be able to finish my app I'll write a detailed tutorial on making apps for iOS because there are several issues to get around to and most of them require messing with the code.
