A class that converts Scalable Vector Graphics (SVG) into:
- CGPaths
- CAShapeLayers
- UIBezierCurves
- NSBezierCurves.
This makes it easy to create vector-based paths and shapes in your iOS or OS X apps.
This a fork of an SVG to bezier path parser by Martin Haywood, with fixes by Pieter Omvlee and Dominic Mortlock.
Feedback, improvements, and pull requests are welcome.
- Make your drawing in a vector graphics editor such as Illustrator, Inkscape, Sketch, etc.
- Save as an SVG.
- Drag and drop it into your Xcode project.
- Follow these easy steps:
//1: Create a PocketSVG object from your SVG file:
PocketSVG *myVectorDrawing = [[PocketSVG alloc] initFromSVGFileNamed:@"BezierCurve3"];
//2: Its bezier property is the corresponding UIBezierPath:
UIBezierPath *myBezierPath = myVectorDrawing.bezier;
//3: To display it on screen, create a CAShapeLayer and set
//the CGPath property of the above UIBezierPath as its
//path.
CAShapeLayer *myShapeLayer = [CAShapeLayer layer];
myShapeLayer.path = myBezierPath.CGPath;
//4: Fiddle with it using CAShapeLayer's properties:
myShapeLayer.strokeColor = [[UIColor redColor] CGColor];
myShapeLayer.lineWidth = 4;
myShapeLayer.fillColor = [[UIColor clearColor] CGColor];
//5: Display it!
[self.view.layer addSublayer:myShapeLayer];
Don't forget to add the QuartzCore framework to your project (here's how) and import it:
#import <QuartzCore/QuartzCore.h>
- An SVG's d attribute – from the SVG specification
- UIBezierPaths - Class Reference
- CAShapeLayers - Class Reference. Tells you which properties of the shape/path can be manipulated.
- Drawing Shapes Using Bezier Paths - From Apple's Drawing and Printing Guide for iOS
- Added support for NSBezierPaths (thanks to mcianni).
- Fixed problem that causes SVGs to render with wrong frame dimensions.
- Fixed problem that causes some SVGs to render incorrectly.
- Fixed parse bug for SVGs with blank spaces in them (thanks to mindbrix).
- Simplified PocketSVG's init method (thanks to johnnyknox).
- Support for SVG's Basic Shapes.
- Support for SVGs with more than one path (currently PocketSVG renders the last path).
- Improve parser efficiency.
- Make it a category on CAShapeLayer?
