JotUI Drawing Framework
Fast and Efficient OpenGL Drawing View
The JotUI framework provides an OpenGL backed drawing view that's used by Loose Leaf note taking app. The view is designed to be fast and memory efficient, provides undo and redo support, and is easily customized.PerformanceBezier
Optimizations and Additions to UIBezierPath
This library brings UIBezierPath class closer in line to NSBezierPath. It also provides dramatic performance improvements for common UIBezierPath operations, including fetching specific elements and inspecting points along the bezier path.ClippingBezier
Intersections between UIBezierPaths
This library calculates accurate intersections points between two bezier paths. These intersections are also used to calculate shapes generated from two intersecting paths, as if one path had cut the other like a pair of scissors.Stretch UIGestureRecognizers
Add Stretch Effects to Your Views
These three custom UIGestureRecognizers and related sample app show how easy it is to create realistic and intuitive stretch effects to your UIViews. These gestures show three different ways to calculate stretch transforms for any view, each giving a unique effect.iOS Hand Shadows
Make Better Demo Videos
Easily add realistic hand shadows to your app to help make better demo and tutorial videos. In the code: shadows to pinch thumb + index finger, index + middle fingers, and a single pointer finger. Example app included showing how to integrate with your gestures.Touch Chart
Simplify and Smooth UIBezierPaths
Unique algorithm for smoothing and simplifying UIBezierPaths by averaging and reducing the path elements.
This framework can auto-detect rectangles, ovals, and circles. It will also smooth and reduce the number of
elements for all other input paths.
UITouch Blue Dots
Show dots onscreen for every UITouch
Drop in code to add onscreen dots for during every UITouch - perfect for recording touch locations for demo videos.
Simple CloudKit Manager
A simple library to add CloudKit messaging to your app
This library and example app provide a simple and functional example of CloudKit push notifications, subscriptions, and custom types. Perfect launching point
for simple CloudKit integrations into your app.
PowerPoint to UIImage
Convert .ppt slides into individual UIImages
Convert slides in a PowerPoint presentation into individual UIImages. Options to control the size and resolution of the output slides. Example app and .ppt file included.App Launch Guide
Step by Step Guide for Launching Your Indie App
This guide is a collection of lessons learned from launching Loose Leaf as an indie iOS developer. The guide walks through what I did right, what I did wrong, and most importantly: what I would do - step by step - if I were to do it all over again.
