SDLayoutDemo
一个稍复杂的图文混排，开题报告，图片大小不一但又要求图片大小自适应，论文，限制最大宽度，使用indexPath缓存行高。支持cell编辑插入、收藏、点赞、置顶、删除功能。
使用indexPath缓存行高，能够支持90%以上的需求，如果数据计算较为复杂，可以对数据预处理+缓存行高，就相对较好了。

如果能够帮助到你，记得给我点个星星✨。谢谢你。哈哈
部分代码如下：
// 插入一行 - (void)InsertRow { if (self.feedEntitySections.count == 0) { [self InsertSection]; } else { [self.feedEntitySections[0] insertObject:self.randomEntity atIndex:0]; NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; [self.tableView insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic]; } } // 插入一组 - (void)InsertSection { [self.feedEntitySections insertObject:@[self.randomEntity].mutableCopy atIndex:0]; [self.tableView insertSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationAutomatic]; } // 删除一组 - (void)deleteSection { if (self.feedEntitySections.count>0) { [self.feedEntitySections removeObjectAtIndex:0]; [self.tableView deleteSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationAutomatic]; } } // 删除指定行 - (void)deleteRowWithIndexPath:(NSIndexPath *)indexPath { if (!indexPath) return; NSArray *feeds = self.feedEntitySections[indexPath.section]; if (feeds.count > 1) { [self.feedEntitySections[indexPath.section] removeObjectAtIndex:indexPath.row]; [self.tableView deleteRowsAtIndexPaths:@[[NSIndexPath indexPathForRow:indexPath.row inSection:indexPath.section]] withRowAnimation:UITableViewRowAnimationAutomatic]; } else { [self.feedEntitySections removeObject:self.feedEntitySections[indexPath.section]]; [self.tableView deleteSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationAutomatic]; } } // 置顶 - (void)moveWithIndexPath:(NSIndexPath *)indexPath { if (!indexPath) return; NSArray *sections = self.feedEntitySections[indexPath.section]; if (sections.count > 1) { [self.feedEntitySections[0] insertObject:sections[indexPath.row] atIndex:0]; [self.feedEntitySections[indexPath.section] removeObjectAtIndex:indexPath.row + 1]; [self.tableView reloadData]; } else { [self.feedEntitySections[0] insertObject:sections[indexPath.row] atIndex:0]; [self.feedEntitySections removeObjectAtIndex:indexPath.section + 1]; [self.tableView reloadData]; } }
