Mailto: links in a PDF, with a prepopulated Body, not working when viewed in iBooks reader

I've designed a brochure for a client using InDesign, exported as an interactive PDF. He wants a simple way to capture info from the reader so I suggested an email link with a prepopulated body. The mailto link contains a Subject and Body, basically like this:

mailto:info@xxxxx.xxx?subject=BlahBlahBlah&body=Thank%20you%20for%20your%20interest.%20Please%20provide%20the%20following:%0D%0DYour%20Name:%0DBest%20Phone%20Number:%0DBest%20Email%20Address:%0DBest%20Time%20to%20Contact%20You:%0D%0DAny%20Additional%20Message:

The problem is, he'd like this PDF to work in iBooks reader but this mailto: link doesn't work. Can't even 'click' on it. It works as expected on a desktop version of Adobe Reader. A mailto: link with a Subject works great, the problem comes in when I try to add the body. Any suggestions on what to try next? Thank you!
