Custom UIView touch area

Hello I have some weird shapes that I need to handle the touchesBegan method on. The issue is that UIViews are square and the only way I could do it is to maybe declare a grid and then check the coordinates. Is there any other way of doing this?

Also, if you have access this talk at WWDC 2012 was pretty awesome with respect to how to handle complex touch events:

Implement hitTest:withEvent: in your UIView subclass. Return YES only if the CGPoint is inside the shape.

Check out this question for polygon shapes: How can I determine whether a 2D Point is within a Polygon?
