iOS UIView/UIScrollView overlay with zoom capability

I have a UIView/UIScrollView with non rectangular sections, let's call them room plans. The UIView/UIScrollView should be zoomable. When the user clicks to a non rectangular region/room, I should be able to detect which region was clicked and let's say open up the detailed floorplan of that particular room. The problem is that 1. when I zoom in and out, the 'button' size must change. 2. the button is not rectangular.

see an example of what I am trying to implement in iOS. http://www.occc.net/ifp/

Any ideas of how to approach this problem are welcome.

Thank!

I was trying to do a similar thing there. What i did was use a UIImageView within a UIScrollView and load the image in the UIImageView.

I did this in my viewDidLoad : 

 scrollMap.minimumZoomScale=1;
 scrollMap.maximumZoomScale=2.0;
 scrollMap.delegate=self;

Then added this function :

- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView
{
    return self.imgMap;
}

This made the image inside the scrollview zoomable with the aspect ratio of the scrollview. It worked for me. You can try, this might work for you too.

Thanks.
