This app involves converting a book into an app. It has rich text (headings, bold, bullets, etc.) and instead of a page flip UI, it would be built in a split view controller. The master (left sidebar) would list chapters and bookmarks. The detail (right side) would have the chapter's contents and it would scroll down until the end of the chapter. Similar to Apple's Mail app on the iPad.
From my research, I can achieve the rich text by using HTML inside a UIWebView. What I'm not sure about is how to get bookmarks to work properly. Because there are no pages, the bookmark would need to be a vertical point in the chapter's content. For example, lets say the user reads half of Chapter 2, i.e. they have scrolled 50% of the way down. They could create a bookmark here.
My initial thoughts are to break the book's content up into "blocks", possibly paragraphs. For each chapter, in the detail view, use a UITableView. In each UITableViewCell, have a UIWebView with the HTML for each block. This way when the user creates a bookmark, we can store the cell's index path.
What would be the correct approach to this app?
