Hard to say, because you never know, when the docs and the behavior disagree (which happens a *lot*), which of them is wrong. But since experimentation demonstrates that just two methods give you 100% complete control over which cells can be reordered (implementation of tableView:moveRowAtIndexPath:toIndexPath: plus the veto power of tableView:canMoveRowAtIndexPath:), I personally am glad it isn't any more complicated. I think of UITableViewCell's showsReorderControl like UITableViewCell's selected property. You'd never set this directly because the cell lives inside a table view and you want the table to manage selection; you don't want to do anything behind the table's back. Similarly, since the table has sufficient power through its data source methods to manage reordering, I don't want to interfere at the level of the individual table cell. m.
