About PSPDFKit for iOS

PSPDFKit is the best framework for working with PDF files on all modern platforms. It includes tools to display PDFs, edit PDFs, create PDFs, create/edit annotations, fill out forms and create/verify digital signatures.

At a Glance

While the amount of API might look overwhelming at first, you usually only need a subset of these classes but have the power to customize almost anything. We chose to expose a lot of API so that every aspect can be customized, however most settings have good and sensible defaults and you don’t need to know about all classes to start using it.

Here’s the list of classes you will most likely use:

Using the PDFConfigurationBuilder.overrideClass(_:with:) method, you can override almost any class of the controller or view layer (using PDFViewController) or the model layer (using Document) with your own subclass. Use this to customize details that are deep within PSPDFKit with minimum effort. You find some examples for this in the Catalog example app.
