- sections
- A set of section identifiers to insert. If a section already exists at a given index, it is moved up down one index location.
- withRowAnimation
- What type of animation to use when inserting the rows (eg. fade in or slide in from left)
UITableView calls the relevant UIKit.UITableViewSource methods immediately afterwards to get the cells and other content to display the visible rows.
When this method is called inside an animation block defined by UITableView.BeginUpdates and UITableView.EndUpdates, any insertions of rows or sections are deferred until after deletions have been processed. This happens regardless of the ordering of the insertion and deletion method calls within the animation block.
