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.

Code Example: An iPhone Springboard Protoype Based On The Apple Watch

Last month I mentioned an extensive Apple Watch GUI PSD Design Kit for those looking to get an early start on designing for the Apple Watch.

Here’s an interesting source code example from Lucas Menge bringing an Apple Watch style home screen to the iPhone called WatchSpringboard-Protoype.

The example provides the same icon layout as on the apple watch, interactivity features, app opening transitions and many nice touches to make things work right on the iPhone.

Example: Using The iOS Facial Gesture Recognition On A Live Video Feed

Previously I mentioned a nice tutorial on using the facial detection feature of the iOS SDK on a live video stream.

Here’s a nice example from Danny Shmueli showing how to use the facial gesture recognition on streaming video added with iOS 7 for detecting blinking, and smiling gestures.

One of the key issues with using this facial gesture recognition feature is that performance, and the example does a nice job of handling this issue. The logic has been nicely extracted so you can use this gesture recognition in your own projects.

Example: A Swift Based Photo Editing Extension Created With The iOS 8 Photos Framework

Last week I mentioned a nice set of source code examples demonstrating usage of many new iOS 8 features.

Here’s a nice source code example submitted by Dariusz Rybicki of a photo editing extension created with the new Photos framework called SwiftMustaches.

The example provides an extension that runs directly within Photos app providing an option for users to add a mustach to a photo using Core Image’s face detection functionality.

Example iOS Source Code: A Full Featured PDF Reader App

I’ve mentioned a number of open source projects for working with PDF files most recently ILPDFKit for working with PDF forms, and BNHTMLKit for easily generating PDF files from a URL or HTML string.

Here’s an open source example pdf reader app providing a full featured book reader style experience called GreatReader from Shohei Miyamoto.

The features of GreatReader include:

- iPhone/iPad Support
- iBooks Like Design
- Zooming in/out with double tap
- Rotation handling
- Reading histories view
- Cropping for zooming
- Document Outlines

Example: An Extensive News Reader App Built In Swift

A couple of months ago I mentioned a nice news reader app created in swift for the hacker news called SwiftHN.

Here’s a complete open source news reader app created entirely in Swift for The Oakland Post from Andrew Clissold.

The app provides an extensive feature set listing stories with image thumbnails, and post times, a nice clean reading experience, and a photo browser. The example utilizes a number of open source projects including the RSS feed parser MWFeedParser, and the asynchronous image downloading library SDWebImage.
