We are happy to announce version 6.10.1 of PDFTron's iOS SDK . This release adds redaction capabilities, form field navigation buttons, and new features for architecture, engineering, and construction (AEC) applications including a file comparison UI control, as well as ruler, perimeter, and area annotation tools.
Redaction
We are pleased to introduce support for redaction with this release. The new
PTRectangleRedactionCreate
and PTTextRedactionCreate
tools allow users to easily select text or a rectangular
region of the document and then permanently redact the contents of that selection.

Please see our redaction tool guide for more information.
PDF measurement tools
There are new tools to create distance, perimeter, and area measurement annotations:
PTRulerCreate
,
PTPerimeterCreate
,
and PTAreaCreate
.
These allow the user
to create measurement annotations and define a translation scale from document
space to world space with a variety of different units. This is especially useful
when working with architectural drawings for example.

Please see our measurement tool guide for more information.
File comparison control
This release includes a new PTDiffViewController
class to
compare two files and create a new file displaying the visual difference
between them.

File attachment annotations
This release introduces support for creating and opening file attachment
annotations. The new PTFileAttachmentCreate
tool handles creation of file attachment annotations, while a
flexible API
handles existing file attachments in documents.
Form field navigation
It is now possible to cycle forwards and backwards through form text fields
on a page. The PTFormFillTool
provides an option to display buttons above the keyboard when filling in forms
to allow the user to quickly navigate between each text field.
