To draw polygon you should use the drawRect method located in UIView subclass.
So 2 solutions :
1°) You subclass UIImageView and in drawRect you draw your image and draw your polylines then
2°) You have an UIImageView and on the top an UIView subclass where you draw your polylines
Drawing the polylines won’t be a problem (you should find an answer on stack).
(like here : polyines on iphone)
