/***
 UIView與核心動(dòng)畫(huà)區(qū)別?
 1.核心動(dòng)畫(huà)只作用在layer.
 2.核心動(dòng)畫(huà)看到的一切都是假像.真實(shí)值并沒(méi)有被修改.

 什么時(shí)候使用UIVeiw,什么時(shí)候使用核心動(dòng)畫(huà)
 1. 什么時(shí)候使用UIVeiw:當(dāng)與用戶進(jìn)行交互時(shí),使用UIView.不須要與用戶進(jìn)行交互時(shí), 使用兩個(gè)都可以.
 2.什么時(shí)候使用核心動(dòng)畫(huà):當(dāng)做幀動(dòng)畫(huà)時(shí),轉(zhuǎn)場(chǎng)動(dòng)畫(huà).
