360° panorama libraries for ios

Are there any libraries or classes out there to show a 360 degree panorama on the iPhone?

I found this here: http://code.google.com/p/panoramagl/ but it's not up to date and only for old versions of ios.

I'm thankfull for any link that helps me to create a 360 degree panorama view on ios.

Check this open source UIView subclass to make awesome interactive 360-180 degrees panorama from 6 images, one for each face of a cube.In the link you can check the example

PanoramaViewer

I've recently found KRPano and since it's not listed here..
