How to show or open PDF documents on iOS devices

We would like the ability to show generated PDF documents in our mobile application. However, the 'Document File Document' action does not work on iOS (regardless of the option 'show file in browser instead of downloading') because Apple does not allow iOS users to download files from the web. The Mendix Document Viewer does not work properly because it can only show the first page of the document (at least it does on iOS 8). Alternatively, is there a way to open the PDF document in another app? For example using URL schemes, or making use of the 'Open with...' functionality of iOS?

I think this question has been answered here. I suggest filling a bug report also.
