What classes and libraries are used in the Skype 5.x for iOS GUI?

Question

iPhone

I decided to study Objective C and everything related to iOS app development. I recently noticed that the Skype application on the iPhone has been updated to version 5.x, and upon launch I saw a pretty cool GUI with great animation. In this connection, the question arose: can anyone tell what classes are used to build such an interface and what can be read to learn how to develop at least a slightly similar interface?

Answer 1

It is difficult to give advice without understanding what your base and experience are,
but specifically on animation you can read here
