endPoint | The end point of the gradient when drawn in the layer’s coordinate space. Animatable. |
startPoint | The start point of the gradient when drawn in the layer’s coordinate space. Animatable. |
type | Style of gradient drawn by the layer. Defaults to kCAGradientLayerAxial. |

Remarks

• Use startPoint and endPoint to change the orientation of the CAGradientLayer.
• Use the locations to affect the spread/positions of the colors.
