iOS UIBezierPath Performance

=====

This code dramatically improves performance for common UIBezierPath operations, and it also

brings UIBezierPath API closer to its NSBezierPath counterpart. For full background of this

repo, checkout [the blogpost explaining what this framework does](http://blog.getlooseleaf.com/post/110511009139/improving-uibezierpath-performance-and-api).

This code was originally part of [Loose Leaf](https://getlooseleaf.com/). Additional components and

libraries from the app [have also been open sourced](https://getlooseleaf.com/opensource/).

## Available as a Swift Package!

Install PerformanceBezier in your project through Swift Package Manager as of v1.3.0!

## What is this?

This framework adds caching into every UIBezierPath so that common operations can

be performed in constant time. It also adds some missing NSBezierPath methods to the

UIBezierPath class.

After linking this framework into your project, all Bezier paths will automatically be upgraded

to use this new caching. No custom UIBezierPath allocation or initialization is required.

For example, by default there is no O(1) way to retrieve elements from a UIBezierPath. In order to

retrieve the first point of the curve, you must CGPathApply() and interate over the entire path

to retrieve that single point. This framework changes that. For many algorithms, this can 

dramatically affect performance.

## Are you using PerformanceBezier?

Let me know! I'd love to know where PerformanceBezier is using and how it's affecting your apps. Ping me

at [@adamwulf](https://twitter.com/adamwulf)!

Also - If you like PerformanceBezier, then you'll _love_ [ClippingBezier](https://github.com/adamwulf/ClippingBezier) - an easy way to find intersecting points, lines, and shapes between two UIBezierPaths.

## Documentation

View the header files for full documentation.

## Building the framework

This library will generate a proper static framework bundle that can be used in any iOS7+ project.

## Including in your project

1. Link against the built framework.

2. Add "-ObjC++ -lstdc++" to the Other Linker Flags in the project's Settings

3. #import <PerformanceBezier/PerformanceBezier.h>

## JRSwizzle

This framework includes and uses the [JRSwizzle](https://github.com/rentzsch/jrswizzle) library, which is

licensed under the MIT license.
