We are excited to introduce version 6.8.5 of PDFTron for iOS. This release includes a standalone viewer component, tabbed viewer component, new APIs for customizing the UI Tools , and more .

Document Viewer Component

With this release, we have added a new drop in viewer component that allows you to easily add a PDF reader/annotator complete with toolbars and settings dialogs. All of the individual components were available in earlier versions of the SDK, but are now bundled into one easy-to-use UIViewController for even faster implementation.

Tabbed Viewer Component

A second drop in viewer component can display multiple documents at once in tabs. The normal and tabbed viewer components can be used interchangeably without any extra setup required.

UI tools customization APIs

With this release, it is possible to show the popup tools menu when tapping the document, as opposed to long-pressing only, as well as control whether default signatures can be saved and applied. The behaviour of the UI tools and controls can be customized with the ToolManager to best suit your needs.

It is now also possible to completely disable certain tools with a simple and easy-to-use API. For example, to disable the text selection tool, simply implement a ToolManagerDelegate method:

func toolManager(_ toolManager: ToolManager, shouldSwitchToTool tool: UIView & PTToolSwitching) -> Bool
    if tool is TextSelectTool {
        return false
    // Allow all other tools.
    return true
