could be an idea, I ve found on the web a tuto explaining how to manage multi-touch event with an image (in order to zoom it), but not with 2 or more sub-views...
i would then have to calculate the place on the screen of both buttons and calculate if the pointer is in one of them. Is this a good approach ?
