<commit_before># JCTiledScrollView

A set of handy classes wrapping UIScrollView and CATiledLayer that aims to simplify displaying large images at multiple zoom scales. The classes and associated demo code should provide a good reference for how to implement CATiledLayer on iOS devices.

### Features

 * Works on both standard and high resolution displays
 * Only provide a single set of tiles; no need for double resolution @2x tiles
 * Demo code and tiles included
 * iOS 4+

### Future plans

 * Handle zooming in both directions
 * Advanced UIGestureRecognizer support (tap, double tap)
 * Support for overlay views
 * PDF / Vector / SVG drawing as an option over bitmap
 * <s>iOS 3 compatibility (it's possible using _drawLayer:inContext:_, but conflicts with UIGestureRecognizer support)</s> - actually, never mind...

### Handy Links
 * Cut your large images into tiles with [Tile-Cutter][5] by [<NAME>][6].

### Further Reading
  * [Subduing CATiledLayer][9] by <NAME> (Cocoa is my Girlfriend)
  * Apple Tech-Note [Thread Safe UIKit Drawing][7] (in iOS 4+)  mentioned at WWDC 2010<commit_msg>go go github markdown<commit_after># JCTiledScrollView
