Alternatively, is it possible to click on a button in the iPad and have it open the PDF using the iPads built in viewer?
I can click into the container and wait for the "Actions" menu to appear and then click "View" but I would like to do this with 1 click.
Did you ever find the answer? I am looking for the answer to this same question. It's discouraging to see that you have not received any replies since April.
Yes, you can do this. Use Export Field Contents and check the "Open Automatically" checkbox. Send it to the temporary directory, and FileMaker can access that on the iOS device.
