Add lines and arrows in Keynote on iPhone
You can create a straight or curved line, then customize its look by changing its width (thickness) or color, or by adding different endpoints—for example, an arrow, circle, or square. Connect two objects with a line so they remain connected, even when they move.
Add and edit a line
Tap , then tap .
In the Basic category, tap a straight or curved line to add it to the slide.
Drag the line to where you want it on the slide.
To change the line length and rotation, drag the blue dots on the ends.
For a curved line, drag the green dot to change the arc.
To modify the style of the line, tap , then tap a line style.
Adjust any of the following:
Stroke Style: Tap Style, then tap a stroke style.
Color: Tap the color well, swipe to see the color options, then tap to select one. (See Fill objects with color or an image in Keynote on iPhone for more information on choosing colors.)
Width: Drag the slider to change the line’s thickness.
Arrowheads: Tap the left or right arrow setting, then tap an arrowhead style.
Shadow: Tap to turn on Shadow, then tap one of the shadow effects.
Reflection: Tap to turn on Reflection, then move the slider to adjust the effect.
Opacity: Drag the Opacity slider to make the line more or less transparent.
Edit line curves and corners
You can edit a curved line to add right-angle corners or curves. As you edit, you can quickly change corners to curves and vice versa.
Tap the curved line to select it, then tap .
In the Style tab, tap Connection, then tap Curve or Corner.
Connect two objects with a line
You can join two objects with a curved, straight, or right-angle connection line. If you move one or more connected objects, they remain joined by the line. This is especially useful if you’re creating a flowchart.
Before you do this task, add two or more objects to the slide that you want to connect.
Select two objects, tap , then tap .
From the Basic category, tap the curved line to add it to the slide.
Do any of the following:
Change the curved line to a straight or right-angle connecting line: Tap the line to select it, tap , tap the Style tab, tap Connection, then tap an option.
Adjust the space between line endpoints and their connected shapes: Tap the line to select it, tap , tap the Style tab, tap Connection, then drag the Outset sliders.
Change the position of the angles or the curve: Drag the green dot (you may need to make the line longer to see it).
You can change the look of the connection line by changing its thickness, color, line style, and endpoints, and by adding effects like a shadow and reflection.
To work with multiple lines at the same time, touch and hold one line, then tap the other lines with another finger.
