Smooth Moves
?
you first ask mover for its animator , and you then send setFrame: to that instead.?

if(isRight) {
[[mover animator] setFrame:leftFramePosition];

Finding Animations
?
first looks in the receiver’s animations dictionary, and if an
animation is found, it is returned. (We will eventually be adding custom
animations to this dictionary in Chapter 3, Animation Types, on
page 28.) If not, then the class method defaultAnimationForKey: is called,
and that animation is returned. The proxy then invokes the animation,
which in turn animates the change for the property.
is not animated; instead, the value is simply passed to the underlying
object.

interpolation between the fromValue and the toValue. By default, the
current value of the changing property is used as the from value, and
the new value is used as the toValue for the animation. The animator
then passes responsibility to an instance of CAAnimation for doing the
interpolation between the fromValue and toValue and animating these
changes.
