Creating a hyperlink that can be clicked on the iPhone via pdf

Yes, that's a mouthful.

I thought that this would be possible, but maybe it cant.

Basically I've made a document in Pages that includes a hyperlink (google maps) to driving directions. The idea is that when someone recieves this document on their iphone, they can then scroll to the bottom, click the link, and get to where they're going with ease.

I save to pdf and the link works on my computer with no problem, but when I email it and view the document on my phone. Nothing. Am I missing a step? Is what I neeed to do not possible?

TIA
