Save a shape to the shapes library in Keynote on iPhone

If you created or customized a closed-path shape, you can save it to the shapes library. When you save a custom shape, the shape’s path, flip, and rotation properties are saved; size, color, opacity, and other properties aren’t.

If you’re signed in to the same Apple Account on all your devices and have iCloud Drive turned on, your custom shapes are available in any Keynote presentation on all your devices (but not in Keynote for iCloud).

Go to the Keynote app on your iPhone.
Open a presentation with a custom shape.
Tap the custom shape to select it, then tap Add to Shapes. If you don’t see Add to Shapes, tap to see more options.
The shape is saved in the My Shapes category of the shapes library, which appears only when you have custom shapes. Shapes appear in the library in the order you create them; you can’t change this order.
In the shapes library, touch and hold the shape you just created, then tap Rename.
Type your own name for the shape.

To delete a custom shape, touch and hold it in the shapes library, then tap Delete.

Important: If you’re using iCloud Drive, deleting a custom shape deletes it from all your devices that use iCloud Drive and are signed in to the same Apple Account.
