Mass uncheck checkboxes in Numbers on iPhone

EvilVW,

There doesn't appear to be a way to handle them at one time on iOS devices like you can on a Mac. If this is a feature you would like to see in the future, you can provide feedback here: Product Feedback

Hi EvilVW,

Let's see if this link helps with what you are trying to do, it goes over selecting different ways to select multiple cells.

In Select tables, cells, rows, and columns in Numbers on iPhone - Apple Support

Select cells

•. Select a cell: Tap it once.

•. Select a range of adjacent cells: Tap a cell, then drag a blue dot across the range of adjacent cells.

 Accessibility Tip: To make a rectangular selection of multiple cells using VoiceOver, select any cell handle. Double-tap and hold, then drag up, down, left, or right to change the selection. VoiceOver speaks the cell selection when you stop dragging the handle.

•. Select nonadjacent cells: Tap a cell, tap it again, tap Select Cells, then tap more cells in the table or drag a blue dot across the cells you want to select. When you finish selecting, tap Done.

•. Select all cells in the table: Tap a cell, tap it again, tap Select Cells, then tap Select All. When you finish selecting, tap Done.

•. Select a cell to add or edit content: Double-tap the cell.

• Select similar cells in a pivot table: Tap a cell, tap , then tap Select Similar Cells. For example, you can select one Total row cell, then tap Select Similar Cells to select them all.
