PocketSVG

An Objective-C class that converts Scalable Vector Graphics (SVG) into:

• CGPaths
• CAShapeLayers
• UIBezierPaths
• NSBezierCurves

This makes it easy to create vector-based paths and shapes in your iOS or OS X apps.

Feedback, improvements, and pull requests are welcome.

Usage

1. Make your drawing in a vector graphics editor such as Illustrator, Inkscape, Sketch, etc.
2. Save as an SVG.
3. Drag and drop it into your Xcode project.
4. 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>

Useful Documentation

• 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

Latest Fixes

• 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).

To Do

• 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?
