CABasicAnimation

 
我们可以通过animationWithKeyPath键值对的方式来改变动画
animationWithKeyPath的值：
 
transform.scale = 比例轉換
transform.scale.x = 闊的比例轉換
transform.scale.y = 高的比例轉換
transform.rotation.z = 平面圖的旋轉
opacity = 透明度
 
margin
zPosition
backgroundColor
cornerRadius
borderWidth
bounds
contents
contentsRect
cornerRadius
frame
hidden
mask
masksToBounds
opacity
position
shadowColor
shadowOffset
shadowOpacity
shadowRadius
