In this chapter, we will cover:
The Core Image framework is a hardware-accelerated framework that provides an easier way for you to enhance your photos and videos using the several built-in filters: color effects, distortions, and transitions, as well as several advanced features: auto-enhance, red-eye reduction, and facial recognition.
In this chapter, we will take a closer look into these frameworks and how these can be used to apply image filter effects using the CIFilter
class, as well as implementing Airplay to allow us to output content to another device using Apple TV. We will learn how to use the AVFoundation framework to record and play back audio content using the iOS device's built-in microphone. Finally, we will learn how we can use the
CoreGraphics framework to enable us to draw shapes, and textual information to our view.
