Add and edit master slides in Keynote on iPhone
The slide layouts used in each Keynote theme are based on master slides. When you want to add a slide to your presentation that has particular elements — such as a title and subtitle, a bullet list, or an image — you select the slide layout that most resembles the layout you want, then you replace the place holder elements and make other changes as necessary. Only the slide in your presentation is changed; the master slide retains its original state.
If you add new images, text and other objects to a master, these objects become part of the slide background and aren’t editable in your presentation. If you want text, shapes or images on a master slide to be editable in your presentation, you must add them as place holders in the master slide.
You can make the same kinds of changes to a master slide that you make to a regular slide — for example, modify the appearance of text, change the slide background and change the size of the images. The changes appear on every slide in the presentation that’s based on that master.
Add a new master slide
Tap any blank area on a slide, then tap Edit Master Slide.
Tap at the bottom of the slide navigator, then tap to select an existing master slide with a layout similar to the layout you want.
If you don’t see the slide navigator, tap Master Slides in the top-left corner of the screen.
Type a name for the new master slide, then tap Done.
Modify the slide however you like by adding text, images, shapes, place holders and other objects.
See “Add text and media place holders”, below.
When you’re done editing, tap Done.
Add text and media place holders
Tap the background of any slide (so that nothing is selected), then tap Edit Master Slide.
Tap to select the master slide you want to edit.
Do one of the following:
Create a text place holder: Add a text box or add a shape.
Create a media place holder: Add an image or add a video.
Change the item’s appearance however you like and drag it where you want it on the slide.
Tap to select the object you added, tap , then tap Style.
Scroll down, then turn on Define as Text Place Holder or Define as Media Place Holder.
If you want slides based on this master to allow objects to be layered under master objects, tap the background of the slide (so that nothing is selected), tap , tap Appearance, then turn on “Allow Layering”.
To learn more about layers, see Layer, group and lock objects in Keynote on iPhone.
When you’re done editing, tap Done.
Place holders are automatically tagged according to type. The tags “tell” the content where to go when you apply a different master to a slide. For example, an image that’s in a place holder with the tag “Media” is automatically added to a place holder from the new master that also has the tag “Media”.
To change a tag, select the place holder, tap , tap Style, then tap Tag. Delete the existing tag, then type your own.
Add an object place holder for a table, chart or image gallery
A place holder you can add a table, chart or image gallery to is called an object place holder. You can add only one object place holder to a master slide.
Tap a blank area on any slide, then tap Edit Master Slide.
Tap to select the master slide you want to edit.
Tap , tap Appearance, then turn on Object Place Holder.
Resize the place holder and position it where you want.
The first table, chart or image gallery you add to any slide based on this master, assumes the place holder’s size and position.
If you want slides based on this master to allow objects to be layered under master objects, tap the background of the slide (so that nothing is selected), tap , tap Appearance, then turn on “Allow Layering”.
When you’re done editing, tap Done.
Delete a master slide
Tap a blank area on any slide, then tap Edit Master Slide.
Tap to select the master slide you want to delete, tap it again, then tap Delete.
If slides in the presentation use this master slide, choose a new master slide for those slides in the dialog that appears, then tap Choose.
Tap Done.
