  • CABasiAnimation的变化属性

    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    背景颜色

        cornerRadius    圆角

        borderWidth
