Buttons in UIScrollView not responding after zoom

[lostInTransit]

Hi

I am using a scrollview and have a UIView inside it (for zooming). The UIView has a UIImageView and some buttons in it (I would like the buttons to zoom with the image)

When the view is not zoomed, the buttons respond to touches as expected (events are fired) but if I zoom the view, the buttons stop responding to events.

Any idea why this would happen? Also if this is a limitation of the scrollview then how can I achieve the function I am looking for (zooming buttons with image)?

Thanks for any help
