Hi ,
I got a problem here , problem is with drawRect: method , i am
using UIViewController class in which i have one PolygonView instance . I
already added this as an outlet in nib file , now what when i am trying to
unwrap CGPoints from NSValue ,which i got from NSArray i could not get that
value .
warning: Unable to read symbols from "UIKit" (not yet mapped into memory).

My Code is :------------
