======================================== 待办 ========================================
功能: 颜色 | 视频 | 链接 | 引言
功能: toolBar 适配（通过 … 实现）
bug: emoji 高度计算错误
bug: 拼音输入过程中高度计算错误
bug: 找到修改 kLineSpacing 会导致整个计算错误的原因。
优化: 草稿，图片缓存优化，没有使用的图片定时清理
优化: 支持斜体。
优化: 图片非编辑状态应该收起
优化: 图片点击之后更丰富的处理
优化: 在选图片 collectionView 上下拉，选中状态会闪烁
优化: 图片前后输入文字处理。
======================================== 完成 ========================================
功能: 草稿
功能: 导出成 HTML
bug: checkbox 后插入图片计算错误
bug: 首行切换 checkbox 后换行显示错误
bug: 中间插入图片后位置不正确
bug: 首行图片后位置计算不正确
bug: 删除图片后位置计算不正确
bug: 连续插入图片位置不正确
bug: 粗体换行好计算错误
bug: 中文高度计算错误
bug: 图片插在 numbering 中间
bug: 行高计算小数精确位数影响结果
bug: 粗体和 underline 时候高度错误。
优化: bullets 换成图片
优化: 居中换行到下一行时，光标位置不正确。
优化: 插入图片时候主线程会卡顿一下，应该图片太大导致。
优化: 粗体换行后继承。
优化: numbering 之间间距太大。
优化: 插入位置为行首时，图片插入在前面
重构: Line 的扩展

## 介绍
LMNote 是原生代码写的富文本编辑器，支持如下功能：
1. 粗体、下划线、删除线
2. 标题、副标题、正文格式
3. 项目符号、有序列表、检查框段落样式
4. 居左、居中、居右
5. 插入图片
6. 草稿功能
7. 导出成 HTML
### 存在问题
由于开发和维护时间较少，仅开发了一个 Demo，未做良好封装且存在一些问题（短期内可能不会解决），但基本功能完整而且支持扩展，各位可以依据自己需要直接拿取所需的代码进行二次开发。
**已知问题:**
1. 拼音输入过程中可能会有布局错误
2. 输入内容中包含 emoji 时布局错误
3. 图片前后输入文字显示错误
4. 粘贴或是全选删除可能出现意外情况
**未完成内容：**
1. 斜体
2. 导出 HTML 上传图片部分代码
3. 草稿存储图片优化
