This chapter covered implicit animations and the mechanism that Core Animation uses to
select an appropriate animation action for a given property. You also learned how UIKit
utilizes Core Animation's implicit animation mechanism to power its own
explicit
system,
where animations are disabled by default and only enabled when requested. Finally, you
learned about the presentation and model layers and how they allow Core Animation to
keep track of both where a layer is
and
where it's going to be.
In the next chapter, we look at the
explicit
animation types provided by Core Animation,
which can be used either to directly animate layer properties, or to override the default layer
actions.
