How to extract UIBarButtonItem Icons from the iPhone SDK?
<p>I'd like to extract the default UIBarButtonItem icons from the iPhone SDK. I imagine they're probably stored in the iPhoneSimulator platform as alpha-channel-only PNGs, but I've yet to find it.</p>

<p>The one I'm looking for is UIBarButtonSystemItemReply. (For those suspicious that there's even a valid use case for this, I'm looking to use this on a table row header where the user can post replies, row-wise)</p>
