问题
I am completely new to chipmunk and I have just been using it for a few days, so I'm guessing this is something pretty obvious, however I cannot find any documentation for this. Is there any callback or method in chipmunk that tells you that 2 given shapes have collided?.
If not is the best way to simply use cgrectcontains on the sprites?.

You can get to it from Ipthnc's link, but this is the documentation you're probably looking for - it details the collision callback system:

Does this help:
http://code.google.com/p/chipmunk-physics/wiki/CollisionDetection
// Reference line
// Does not collide with other objects, we just want to draw it.
shape = cpSegmentShapeNew(staticBody, cpv(-320,0), cpv(320,0), 0.0f);
shape->collision_type = 1;
cpSpaceAddStaticShape(space, shape);
// Add a collision pair function to filter collisions
cpSpaceAddCollisionPairFunc(space, 0, 1, NULL, NULL);
Finally, use Google Code Search:
