Core Animation Extensions To Key-Value Coding ，animationWithKeyPath 的取值，CABasicAnimation 动画

[CABasicAnimation animationWithKeyPath:@"opacity"];

animationWithKeyPath后面的属性必须是CALayer的某项属性

animationWithKeyPath可以是如下集中属性：

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
