Summary

It’s hard to believe, but in the span of an hour, you’ve learned about nine new media classes, three protocols, and a handful of class methods and properties. These will provide much of the functionality you need to create applications that handle rich media. The AV Foundation framework gives us a simple method for recording and playing back high-quality audio streams. The Media Player framework, on the other hand, handles streaming audio and video and can even tap into the existing resources stored in the music library. The easy-to-use UIImagePickerController class gives us surprisingly straightforward access to visual media and cameras on the device, while Core Image allows us to manipulate our images with ease.

Because there are many more methods available in the Media Player and Core Image frameworks, I recommend spending additional time reviewing the Xcode documentation if you are at all interested in building multimedia applications using these technologies.
