Question

I have an NSRect being drawn on my custom view and I have another xib with a custom view and a draw rect that is on top of my other NSRect. My question is is it possible to have the NSRect on top see through the one underneath it like creating a hole on the view underneath?

Answer 1

CGRect b=CGRectMake(40, 50, 240, 150);
CGRect c=CGRectMake(100, 125, 80, 275);

 CGRect i=CGRectIntersection(c, b);

i is intersection rect now you can make UIView and set alpha of that view
