Is it possible to change the coordinate system in a UIView so that (0,0) will be the top right hand corner?
My answer bars the use of Interface Builder, but I know of no other way.
After initiating the UIView, perform a CGAffineTransform as such:
Check the documentation for CGAffineTransform. You might also have to translate the view a bit, although I believe it should be good.
The “-1” up there inverts the x coordinate system. Whenever you present a new view programmatically, it will work as you hope.
Cheers!
