I have an app I am working on and several of the touch zones or buttons
occur within a trapezoid. Because these trapezoids touch one another to
complete a picture I need for the zones to be precise. What I'm not sure how to
accomplish is allowing touch within the border of the trapezoid

The easiest way to do this is to create an NSBezierPath in the shape of the
trapezoid and call -containsPoint: on it; but IIRC, that class doesn't exist
on iPhone. Fortunately the math for hit-testing convex polygons is pretty
easy: check any

Another simple approach is to use an image to do hit testing.
You can either create a bitmap image for each touchable area, or
a single image with a different color for each target, then test
the color

I really like the sound of this solution. I've never worked with CGPaths, is
that anything at all like NSBezierPath?
because it seems like this might be the way to go. Can I use an Image to
create a CGPath?
No.
