PocketSVG

A library that converts Scalable Vector Graphics (SVG) data into CAShapeLayers and UIBezierCurves. This makes it easy to create vector-based paths and shapes in your 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. Please get in touch if you can help improve the code.

Usage

Draw your bezier path 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 *myBezier = [[PocketSVG alloc] initFromSVGFileNamed:@"BezierCurve1-iPad"];
    
    //2: Its bezier property is the corresponding UIBezierPath:
    UIBezierPath *myPath = myBezier.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 = myPath.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>
