From Anyone Can Create an App by Wendy L. Wise
Storyboards are a little bit like what they sound like – a way to visualize a story and how the parts of the story are related. If you imagine a graphic novel (I’ve heard that’s what the cool kids are calling comic books these days), there are multiple panes that tell a story. Each pane flows into the next so the reader can follow the story. Imagine if you were writing your own graphic novel – you could start out with several blank panes and lay them out so you could begin planning the novel. You might sketch in a few details on each pane to start, and then you might begin filling in more details as time progresses.

The Core Graphics framework is written in pure C, meaning that it’s impossible to use CGImage instances directly with UIKit. Apple created UIImage as an Objective-C wrapper class around CGImage to bridge the gap. We explore Core Image in this article.
The iPhone, iPod, and iPad are great music playing devices and allow you to create playlists. Creating playlists is useful, but being able to play them is necessary to really make it worthwhile. So using the iPod access to select tracks, CoreData to store the selections, and the music player to play the music makes for a usable app. To start, you need to design a database within Xcode and have the related code generated for you. In this article based on chapter 7 of iOS in Practice, author Bear Cahill shows you how to set up the project to support a table view navigation.
