Matrix transformations can make your user interfaces come to life: translate, scale, and rotate. Each on its own is relatively simple and straightforward. Yet many developers are daunted when 2 or more operations need to be combined. What if you need to rotate or zoom about an off-center (or even off-screen) point? How do you combine multiple transformations into a single animation? How do you make advanced, polished 3D animations such as folding and flipping views? Learn everything you need to know to get started with complex matrix transformations in CoreGraphics and CoreAnimation and take an in-depth look at folding and flipping animations. We'll also cover related topics such as anti-aliasing, avoiding off-screen render passes, shadows, and rendering retina images. Tons of demos and full open-source source code provided.
