The Audio Toolbox framework provides interfaces for recording, playback, and stream parsing. In iOS, the framework provides additional interfaces for managing audio sessions.

Core Audio is the digital audio infrastructure of iOS and OS X. It includes a set of software frameworks designed to handle the audio needs in your applications. Read this chapter to learn what you can do with Core Audio.

The Core Graphics framework is based on the Quartz advanced drawing engine. It provides low-level, lightweight 2D rendering with unmatched output fidelity. You use this framework to handle path-based drawing, transformations, color management, offscreen rendering, patterns, gradients and shadings, image data management, image creation, and image masking, as well as PDF document creation, display, and parsing.

Core Video provides a pipeline model for digital video. Partitioning the processing into discrete steps makes it simpler for developers to access and manipulate individual frames without having to worry about translating between data types (QuickTime, OpenGL, and so on) or display synchronization issues. Applications that do not need to manipulate individual video frames should never need to use Core Video directly.

ObjectAL for iPhone is designed to be a simpler, more intuitive interface to OpenAL and AVAudioPlayer.

Record or stream video from the screen and audio from the app and microphone, so that users can share their experiences through email, messages, and social media.

Use the Safari Services framework to integrate Safari behaviors into your iOS app.

Secure the data your app manages. Protect information and control access to your app.

The Social framework lets you integrate your app with supported social networking services. On iOS and OS X, this framework provides a template for creating HTTP requests. On iOS only, the Social framework provides a generalized interface for posting requests on behalf of the user.

This collection of documents describes the programming interfaces of the System Configuration framework. The System Configuration framework provides functions that determine the reachability of target hosts in both a synchronous and an asynchronous manner. It also provides error detection facilities.
