SDK 化收尾: - 新增 RDPDFReaderView 本地 pod(阅读容器、成品控制器、划线/注释、画笔、 目录/设置面板、主题与持久化契约),Demo 精简为 PDFKit 页面提供者 + 持久化宿主 - Podfile/工程接入 RDPDFReaderView 与 SnapKit,示例书改用 PDF 阅读器示例文件 手机横屏单页竖滑修复: - cell 高度改为宽度适配后的纸张高度(sizeForItemAt + 宿主按页提供纵横比), 纵向超出一屏的内容由外层 collectionView 连续滚动承接,不再被裁掉 - 页面内部不再开启同向嵌套的兜底竖向拖动,修复外层滚动被吞、无法滚到下一页 - 修复 applyContentSize 先评估拖动开关后写 contentSize 的顺序缺陷 - 页码按视口中心命中 cell 计算,补 didEndDragging 兜底;旋转重锚点与 transitionToPage 改用真实布局位置 - 横竖屏同为竖滑时也重建 cell 并刷新全部可见页的适配配置 - 横屏单页点击不再跳页,只显隐工具栏;翻页交给连续竖滑 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
