A simple free-drawing app for iOS
ColoredBezierPath is a subclass of UIBezierPath with an added property to keep track of color with a UIColor property.
DrawingView uses the touch-event methods to track user touches and draw a path that follows the user's finger.
It's a drop-in class that will work as soon as it's placed in a view with the following customizable properties:
- pathWidth
- pathColor
