Perhaps you could use separate images and convert them to
monochrome, saving them as 1 bpp bitmaps (aka masks). Memory
should not then be an issue.

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 at the target point to determine membership. My only
concern with using this approach on iPhone might be the memory
usage of that image.
