We are happy to announce the latest release of PDFTron's iOS SDK, which includes refreshed PDF components, data-saving PDF streaming, improved bookmark handling, and more.

Refreshed UX

PDFTron's UI components have been updated with a fresh new look:

Document ViewerThumbnails ViewerNavigation Lists

Changes include much improved visuals, re-positioning the buttons to open the thumbnails and annotation/outline/bookmarks to next to the page slider, plus new subtle animations.

Bookmark saving

In this new version of the SDK, user bookmarks are saved directly into the PDF. This means that PDFs that are sent and shared between different versions of PDFTron, on different devices and platforms, will have their bookmarks preserved.

And more...

Please see our change log for a list of all changes.

We hope you like these changes and any feedback is greatly appreciated. Please don't hesitate to contact us if you have any questions or suggestions. We also have many exciting new features planned for the coming weeks and months. Stay tuned...
