KNSemiModalViewController

UIViewController+KNSemiModal Category

UIViewController+KNSemiModal is an effort to make a replica of semi-modal view with pushed-back stacked animation found in the beautiful Park Guides by National Geographic app. You can see this original semi-modal view below.

This library (ARC) is designed as a Category to UIViewController so you don't have to subclass and you can simply drop in any project and it will just work!
