A set of handy classes wrapping UIScrollView and CATiledLayer that simplifes displaying large images and PDFs at multiple zoom scales. The classes and associated demo code should provide a good reference for how to implement CATiledLayer on iOS devices.
- Supports Bitmap tiles, and PDF files through two seperate classes
- Works on both standard and high resolution displays (hellooooo retina display iPad!)
- For bitmap images you only need toprovide a single set of tiles, no need for @2x tiles
- Demo code, tiles, and example PDF file included
- iOS 4+
- Merged experimental PDF rendering classes into the main project. Welcome JCTiledPDFScrollView.
- Handle zooming in both directions
- More advanced UIGestureRecognizer support
- Support for overlay views
- Cut your large images into tiles with Tile-Cutter by Jeff La Marche.
- Cut your images on the command line with my fork of Chris Miles' experimental SliceTool program.
- Subduing CATiledLayer by Matt Long (Cocoa is my Girlfriend)
- Apple Tech-Note Thread Safe UIKit Drawing (in iOS 4+) mentioned at WWDC 2010
- Tread safe objects in iOS4 UIGraphicsGetCurrentContext, UIImage, UIColor, UIFont
- Apple Documentation on Supporting High Resolution Screens
- Apple's View Programming Guide for iOS
- WWDC 2010 Session 104 - Designing Apps with ScrollViews
- WWDC 2011 Session 104 - Advanced Scroll View Techniques
