Is there any iOS projects that create dynamic grid layouts?

There is a javascript example here http://vnjs.net/www/project/freewall/example/fit-zone.html

Its github page is https://github.com/kombai/freewall

Another example is here: http://isotope.metafizzy.co/layout-modes.html

I want to known if there is some project with Objective version on iOS.

Thank you.
