CALayer Animatable Properties 之animationWithKeyPath

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
