In this article I will explain how to do face detection on a live video feed using an iOS 5 device. We will be using Core Image to do the heavy lifting. The code is loosely based on the SquareCam sample code from Apple. 
I’ve mentioned some excellent open source games from the app store that could be used as a great examples for learning how to create games. Most of these games use Cocos2D and I’ve come across another Cocos2D game that makes for a great example. 
In a previous post, I mentioned a way of thinking about interactions and interface within a framework of depth and space. The ideas were centered around the digital space, but as a designer I find it’s important to remove myself from that space and explore solutions that can originate in physical space. One of the easiest ways to do this is to break out scissors and paper. With paper you can remove the constraints of working in pixels to fold, tear, flip, curl and manipulate the medium to discover solutions that may have otherwise been missed. To illustrate this, I created a few examples based on some familiar apps and others based on former concepts I’ve played around with in the past.

One of the great new features of iOS 5 is the addition of the Core Image (CI) framework. This framework has been available for a few years on the Mac, but now its advanced image processing and filtering capabilities are available on the iOS platform as well. One particularly cool new feature available in Core Image, on both iOS 5 and Lion, is its ability to detect faces in an image. Via Alessio Nonni 
100 Tools to Develop the Next Killer iOS or Android App I’ve mentioned some great libraries in the past created to make Objective-C development quicker and easier such as a library that dynamically enables block based calls, and this massive collection of Objective-C utility classes. ✔ Sources: https://github.com/acburk/SOCQ 
This tutorial is on adding an intro view to your app. In this instance we’ll be adding it to a tab bar app. This is not the use of a splash view Peertalk is a iOS and OS X Cocoa library for communicating over USB and TCP/IP. ✔ Sources: https://github.com/rsms/peertalk 
The aim of this tutorial is to show how to add iCloud support to a project. The starting point will be the final project from the end of the Core Data Universal / iPad Storyboard tutorial. I would recommend going through that tutorial first so you’re familiar with the Staff Manager project. |
Here is a method I recently devised for getting YouTube videos to work in a useable and clean way within iPhone Apps. 
UIViewController+KNSemiModal is an effort to make a replica of semi-modal view with pushed-back stacked animation found in the beautiful Park Guides by National Geographic app. You can see this original semi-modal view below. This library (ARC) is designed as a Category to UIViewController so you don't have to subclass and you can simply drop in any project and it will just work! ✔ Sources: https://github.com/kentnguyen/KNSemiModalViewController 
Adjusting the size of a UILabel is a pain in the back. This category provides a couple of simple methods to make this process less painful. You can "auto adjust" a label provided a minimum size, maximum size or none at all.

MGTileMenu is an iOS GUI component, providing a pop-up tile-based contextual menu. It's designed for iOS 5, and uses ARC. It supports Retina and non-Retina devices, and works with VoiceOver. MGTileMenu is designed for use on iPad, but it will also work on iPhone and iPod touch.. ✔ Sources: https://github.com/mattgemmell/MGTileMenu 
In this example, we will see how to make a UIButton control behave as a two – state toggle switch. 
LIExposeController is a new navigation paradigm for iOS apps. A great example is LinkedIn's iPhone app. LIExposeController acts as a container view controller, much like UINavigationController or UITabBarController. It manages a set of UIViewControllers as separate "stacks" so that users can easily switch between multiple screens.

MOOPullGesture - Clean, versatile pull gesture for iOS perfectionists. Comes with pull-to-create and pull-to-refresh. ✔ Sources: https://github.com/peyton/MOOPullGesture 
OCCalendar is a very simple component for iPhone/iPad that provides a "Popover" date picker controller. It is very easy to add to your project, and is 100% CoreGraphics code, so it uses no images, and is resolution independent. I realize that I need to cut down the size for iPhone a bit more. I originally wrote it just for iPad, and my paths and sizing are all just slightly too wide for the iPhone. I'll fix it when I get a chance.
