iOS Development Source Code Examples

This section is for app source code examples and code snippets that do not come with an in-depth tutorial.

Example: Creating A Drawing App With Really Smooth Curves

A couple of years ago I mentioned a guide on really smooth user drawn lines inspired by the Paper app.

Here’s a smooth drawing example app and guide submitted by Simon Gladman that uses hermite spline interpolation to draw curves between touch points called SmoothSCribble.

The example provides two views allowing you to see how drawing is using Hermite Spline Interpolation to draw bezier curves, and another with regular drawing.

Extensive Source Code Collection Showing How To Utilize Many Features Added With iOS 9

Last year with the release of iOS 8 I mentioned an extensive set of examples demonstrating how to utilize many of the new features added with iOS 8.

Here’s an open source project from Shuichi Tsutsumi providing a number of examples on using many of the new features added with iOS 9 including:

An Open Source WatchKit App With A Great Interface

Last month I mentioned a nice collection of example projects for learning to use WatchKit.

Here’s a nice example of an open source app that uses WatchKit with a great interface called Gulps from FancyPixel.

Gulps is available on the app store, and was created so the user could quickly track and visualize their water consumption. The app uses the previously mentioned DPMeterView to create the custom water tracking meter and also AMWaveTransitions for the wavy transitions.

A Set Of Apple Watch Example Projects For Learning WatchKit

Earlier this year I mentioned a nice WatchKit code example of a time management app inspired by the Pomodoro technique.

Here’s a nice set of example projects from Konstantin Koval created to aid in learning WatchKit development.

The examples include:
