animate an entire view into or out of view to draw attention to it, especially on the
iPhone, but don't move buttons and text fields around on the screen for visual effect.
This is just annoying and will seem more like a practical joke to your user than anything.
But in the end, you need to decide what you shouldn't animate in your application. If
you are not certain whether an animation makes sense, have someone use it and see how
she reacts to the animation. That will get you much farther than any design rule this
book offers.
What you can animate is limited to what Core Animation provides. Fortunately, it
provides everything you need and probably nearly everything you would want. What you
should animate, well, let's face it—that is entirely up to you. We hope that you'll adhere
to the simple principles we've discussed, but we trust that whatever you build you'll build
because you're inspired to make beautiful and useful software.
