SHOW A PDF FILE IN IPHONE/IPAD

Hi SAP Super heroes

I'm trying to open a PDF in a link in the iphone C4C application.

A button was created and this button has an URL to show the PDF file when clicked.

for the example the URL is fixed, but this has to be binded to a field because this is going to be dynamic.

when this is executed in a PC it WORKS well

BUT is you execute this in the iphone APP:  nothing happen

Any idea to achieve this in our mobile app?.

thanks a lot for you help
