Answer 1

Apple has a few videos from their 2010 WWDC session on animation along with the projects shown. They can be found here: https://developer.apple.com/videos/wwdc/2010/

The ones related to animation are:

• WWDC 2010 Session 123 – Building Animation Driven Interfaces
• WWDC 2010 Session 424 – Core Animation in Practice, Part 1
• WWDC 2010 Session 425 – Core Animation in Practice, Part 2

Answer 2

Sparrow是一个出色的开源动画框架（它更像是2D游戏引擎，但是它是用纯Objective-c编写的，因此您可以将Sparrow和Cocoa混合使用），您可能想看看它。
