🚀Mobile React: 全量组件视觉升级

[anlyyao]

发布正式版本之前，需要对所有组件的视觉、交互、示例进行全新升级。

认领 && 贡献流程

• 评论认领组件
• 前往组件关联的 issue，查看开发指引和任务清单，
• 按任务清单对组件进行升级

Tips

• 每次只能认领一个组件
• 有不懂的地方可以随时联系 @Wen1kang or @jarmywang or @anlyyao

认领方式：直接评论 “我来负责xxx组件” 即可。

激励

参与共建的开发者，将可以获得 TDesign 周边（贴纸、鼠标垫、工卡套等）；

成为核心贡献者，将会拥有 TDesign 专属头像。

具体进展

• 对标 Mobile Vue 端（存量组件 41 个，新增组件 19 个，共计 60 个组件）
• 优先级默认从上到下，先存量后新增
