I've prepared a checklist for air travel with our two kids. Currently everything is ticked but I want to reset it for our next trip. Is there a way to untick everything in one go, or do I have to first go untick every item manually?
You can uncheck checked items in the iOS Notes app using the following hack.
1. Select the checklist of items you want to be unchecked.(This can include either checked or unchecked items.)
2. Remove the check-mark format. (After doing this, the items should remain selected, which is good.)
3. Add the check-mark format to the selected items.
4. Deselect the items.
Unfortunately, I haven’t found a more elegant way to do this, but at least it works.
This became possible natively in iOS 13. From the docs:
Manage items in the list: Tap the list to see the menu, tap the Show More Items button, tap Checklist, then tap Check All, Uncheck All, Delete Checked, or Move Checked to Bottom.
It only works for contiguous checkboxes, not lists separated by other text. (Credit to this r/ios post for the lead.)
