An open-source PDF reader/viewer library for iOS written in Objective-C, providing a complete PDF viewing component with multithreaded rendering, password-protected PDF support, and iBooks-like navigation. The project is explicitly no longer supported or maintained and is kept only for historical reference.

Use cases

  • display pdf files in an ios app
  • embed a pdf viewer in my iphone app
  • render large pdf documents on ios
  • open password-protected pdfs in ios
  • add page navigation and thumbnails to a pdf reader app
  • build a pdf viewer app for ipad

When to choose

  • you need a self-contained, code-generated (no XIB) PDF viewer for older iOS versions
  • you want to study a classic Objective-C PDF rendering implementation
  • you must support very old devices and iOS 6+ for legacy projects

When to avoid

  • you are starting a new project - it is unmaintained and the author recommends UXReader-iOS instead
  • you need modern iOS/Swift support or ongoing bug fixes
  • you need PDF editing, annotation, or form-filling features
