Core Animation
Render, compose, and animate visual elements.
Overview
Core Animation provides high frame rates and smooth animations without burdening the CPU or slowing down your app. Core Animation does most of the work of drawing each frame of an animation for you. You’re responsible for configuring the animation parameters, such as the start and end points, and Core Animation does the rest. It accelerates the rendering by handing over most of the work to dedicated graphics hardware. For more details, see Core Animation Programming Guide.
