UIView zoom and draw issue

Question

Hi everyone!

I have UIView wich have to be zoomed in

After zooming i have to draw on this view and then zoom out. And certainly the zoom out picture have to include new drawing in proper size.

So the question is -How can i zoom UIView (or maybe i should use UIImageView instead, then the question is how can i draw on UIImageView) -And how can draw and zoom this view properly

Any suggestion, references, idease and of course sample code will be highly desirable.

HELP,HELP,HELP!!!
