Animate objects on a slide in Keynote on iPad – Apple Support

Animate objects on a slide in Keynote on iPad. You can use action builds to animate an object on a slide. For example, you can have an object move from one side of the slide to the other, make it become transparent, make it blink or bounce for emphasis, and more. You can apply multiple action builds to an object and specify their order to create interesting effects.
