CoreTextArcView.h

/*
 
 File: CoreTextArcView.m (iOS version)
 
 Abstract: Defines and implements the CoreTextArcView custom UIView subclass to
 draw text on a curve.
 
 Based on CoreTextArcView provided by Apple for Mac OS X https://developer.apple.com/library/mac/#samplecode/CoreTextArcCocoa/Introduction/Intro.html
 
 Ported to iOS (& added color, arcsize features) August 2011 by Alec Vance, Juggleware LLC http://juggleware.com/
