15 | 16 | -支持搜索关键词标签加亮以及关键词颜色自定义,设置key字段的值即可 17 | 18 | -标签样式更改tagAttribute,tagSpace是标签内部左右间隔和，还有titleSize，这2个参数影响到计算 19 | 20 | -标签布局计算属性更改layout,即更改HXTagCollectionViewFlowLayout的属性，包括.scrollDirection .itemSize .minimumInteritemSpacing .minimumLineSpacing .sectionInset等属性，用法同UICollectionViewFlowLayout;
