How can I load vector image directly with iPhone SDK?

How can I load vector image directly with iPhone开发者_C百科 SDK? Just as UIImage loads bitmap images.

I did this recently using PDF. I saved some resolution independent images directly from Illustrator (using the smallest file size preset). I have some code (gists) here.

As of iPhone OS 2.1, the iPhone's WebKit supports SVG graphics natively. You should be able to use a UIWebView to load the SVG element for display. This question provides some sample code for doing so.
