Chapter 5. Layer Programming with Quartz Core

The Quartz Core framework is referred to as Core Animation on the Leopard desktop. Quartz Core provides the underlying classes for managing the layers of UIView objects. It is also used to create 3D transformations of 2D objects for stunning animations and effects.

To use the Quartz Core framework, you'll need to add it to your Xcode project. Right-click on the Frameworks folder in your project, and then choose Add Framework. Navigate to the QuartzCore.framework folder, and then click Add.

To find the Quartz Core framework, you may have to navigate manually into either /Developer/Platforms/iPhoneOS.platform or /Developer/Platā forms/iPhoneSimulator.platform and locate the Frameworks folder in your SDK.
