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.
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.
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.
These tutorials spur from my frustration at the current state of affairs with tutorials online. I hope these tutorials impart not only how but why I’ve designed things this way.
