The easiest way to wrap PowerPoint text on iPhone is to employ text boxes: As a line of text gets closer to the object’s left side, use the tab or spacebar multiple times to position the rest to the object’s right side. Alternatively, you can right-click on the graphic and press “Send to Back.” If this option appears grayed out, it already applies to the graphic.
Choose the image or other graphic on your slide the text will wrap around.
