天气折线图📈渐变色
原理：两种方法：
（1）、直接全view（绿色部分的view）设置渐变色
CAGradientLayer，再将贝塞尔曲线的path上边部分加上一个CAShapeLayer进行遮挡覆盖，将其CAShapeLayer颜色设置成和背景色相同的颜色。
（2）、使用gradient.mask = bottomLayer;设置mask 遮罩图层（添加这个，将遮挡gradient.path边界之外的内容）
第一种：这里就不在重复了，可以点击链接查看其实现过程-->>
第二种：1、先看效果图，左边是添加
mask，右边则是不加的效果（注意：layer.lineWidth 线宽是layer在设置贝塞尔path描绘之后的边界线的宽度，实际边界是lineWidth的中间位置，所以下边设置为2时，渐变色要在path位置的Y轴的1位置）
2、gradient.frame = self.chartContentView.bounds;(这样也可以，设置mask时，将path路径外的遮罩住，但是在lineWidth边线的中间，视觉效果时看到了线宽的一半，真正边线的边界开始遮挡的)

本文还要着重研究的是CALayer的mask属性
首先mask是CALayer的一个属性，它本身也是一个CALayer类，但是mask比较特殊。当一个CALayer当做mask遮罩层时，那么这个CALayer的color属性就没有效果了；影响显示效果的透明度。其中backgroundCorlor可以设置透明度，而contents赋值为图片时，图片也是要区分有无透明通道。
比如layer1.mask = layer2,那么layer2就是遮罩图层，layer1就是被遮罩图层。
当layer2为透明(透明度为0)时，遮罩区域将不会显示出来；
当layer2为不透明(透明度为1)时，遮罩区域将会显示出来；
而当layer2为半透明(透明度为(0-1))时，遮罩区域也将会是半透明。
