PDFTron for iOS is available via CocoaPods. The CocoaPods package does not include sample code or source code for the UI framework Tools.framework — please use the manual download for these.
To integrate the PDFTron SDK with CocoaPods, contact us, and then visit this page from the link provided in the email. (This is an automated process and is fast to complete.) The full instructions will then be available here.
Note: CocoaPods distributes the dynamic framework only. If you wish to use the static framework, you will have to integrate it manually.
