1.shadowPath: 设置 CALayer 背景(shodow)的位置2.shadowOffset: shadow 在 X 和 Y 轴 上延伸的方向，即 shadow 的大小3.shadowOpacity : shadow 的透明效果4.shadowRadius: shadow 的渐变距离，从外围开始，往里渐变 shadowRadius 距离5.masksToBounds : 很重要的属性，可以用此属性来防止子元素大小溢出父元素，如若防止溢出，请设为 true6. borderWidth 和 boarderColor : 边框颜色和宽度，很常用7.bounds: 大小，与position 阅读全文
