A project to help me figure out how to save smooth path information to a CALayer and display it on the screen

Freeform Drawing in iOS

This sample project demonstrates how to draw freeform lines in iOS. Based strongly on: http://stackoverflow.com/questions/5076622/iphone-smooth-sketch-drawing-algorithm

The main classes are

  • MotionTrackingViewController.h/m View Controller that adds a pan gesture recognizer to the screen and conveys the information to the drawing delegate, FreeformLineDrawer. This controller also creates a layer that is added to the view.

  • FreeformLineDrawer.h/m Drawing delegate for the CALayer. Maintains a CFMutableArray that keeps track of all the paths that have been drawn onto the screen. Keeps track of paths that have been added.

Contributions are welcome.
