In-Depth Information
Basic animation is known as
single keyframe animation
. This definition helps to explain
what keyframe animation provides. The keyframes in an animation are like a list of what
CABasicAnimation
refers to as its
toValue
field: the destination value. A list of these
values can be supplied to the keyframe animation using either the animation's
values
field or its
path
field. Each of these values are destinations that the animation reaches at
some point in its duration.
Keyframe animation provides a powerful way to animate any animatable layer property
using a simple list of values, making it easy for the developer because the in-between
values are automatically interpolated. This simplicity makes it a snap to create animation-
based user interfaces informative, intuitive, and easy to implement.
