IPhone : look for ready-to-use UIViewController for viewing images in iOS

I am working on an iOS app that needs a view controller that can show full images supporting: pinch-to-zoom, double-tap-to-full-size, paging to the next/prev image.

As these features are very common for most apps that display images, I was wondering if there is a ready-to-use open source UIViewController that supports these features.

If not, I will move ahead and create it myself. But wanted to check first.

thanks.
