Animations

Animations provide fluid visual transitions between different states of your user interface. In iOS, animations are used extensively to reposition views, change their size, remove them from view hierarchies, and hide them. You might use animations to convey feedback to the user or to implement interesting visual effects.

In iOS, creating sophisticated animations does not require you to write any drawing code. All of the animation techniques described in this chapter use the built-in support provided by Core Animation. All you have to do is trigger the animation and let Core Animation handle the rendering of individual frames. This makes creating sophisticated animations very easy with only a few lines of code.
