Core Animations-Drag and Drop

Welcome to the next level in computer animation. No, it’s not a feature film — it’s your desktop. Core Animation is a framework that makes it simple for Mac developers to add visually stunning user interfaces, graphics, and animations to applications. Without any advanced graphics techniques, you can create fluid, stutter-free effects and experiences as groundbreaking as Time Machine and the new Dock.Order from depth.
Using Core Animation, Mac developers can create snazzy animations in their programs using different media types, such as text, 2D graphics, OpenGL renderings, and video, simultaneously. These items are placed on layers, and a scene can contain a few layers or thousands of layers, each with its own content. Core Animation can add different effects to layers, then composite and render them in real time. When content changes, Core Animation updates it automatically.
Two heads are better than one.

Core Animation performance benefits from multiple cores in the latest Intel-based Mac computers. When developers use Core Animation in an application, the framework can take advantage of processor threads. On a multicore Mac, that means the application runs on one core, and Core Animation graphics tasks run on the other.
Shift from manual to automatic.

No need to create animations by managing individual elements on a frame-to-frame basis. Just describe the start state, the end state, and any interim states or keyframes, and let Core Animation do the rest. You can also describe how your animation should react to user input, and it adjusts accordingly. Core Animation opens up the power of Apple’s graphics technologies and proven aesthetics to every developer. You’ll be seeing its effect in a new generation of amazing apps to come.
