Create a clickable image map on iPhone

I wanted to create a clickable map for the United States, when user select a state it will be highlighted and display another detailed view.Like the following web开发者_如何学Python application.

I would appreciate any suggestion on how this can be achieved on a native iPhone application.

Thanks in advance, Sarah

Have a look see here: http://www.iphonedevsdk.com/forum/iphone-sdk-development/27988-hidden-buttons.html

It's a step in the right direction, I'd too be interested in an example doing it via code.

There's a new app that you can do this with for free. It makes a customizable US map http://createaclickablemap.com/
