Can you lock a fillable PDF on ipad?

[LouiseW2]

I have a fillable PDF used for invoices. I would like to lock this PDF so the fields can't be edited. Is this possible to do on a iPad? Please help!

If you're asking about using the Acrobat Reader mobile app in an iOS device,  the Acrobat Reader mobile app introduced  "Set Password" as a new feature to lock the PDFs in the last update.

If what  you're really  asking is  how to do this on an iPad without using  the Acrobat Reader app, that is something I would suggest to consult directly with your Apple support forums, AND, more importantly, for your particular device.
