6. Assembling Views and Animations > Recipe: Using Core Animation Transitions

Recipe: Using Core Animation Transitions

In addition to UIView animations, iOS supports Core Animation as part of its Quartz Core framework. The Core Animation API offers highly flexible animation solutions for your iOS applications. Specifically, it offers built-in transitions that provide the same kind of view-to-view changes you’ve been reading about in the previous recipe.

Core Animation Transitions expand your UIView animation vocabulary with just a few small differences in implementation. CATransitions work on layers rather than on views. Layers are the Core Animation rendering surfaces associated with each UIView. When working with Core Animation, you apply CATransitions to a view’s default layer ([myView layer]) rather than the view itself.
