AmazeKit is an image rendering library for iOS. Its goal is to retain the performance of using .png-formatted images in UIKit classes, while avoiding the chore of creating these images in Photoshop, as well as the extra download size of bundling the images in the app.

AmazeKit also offers convenient UIKit support, automatically using the correct images as your controls change size. Retina displays are supported automatically, and AmazeKit aggressively caches rendered images to maintain optimal performance levels.
