Editing table views


Table views are not meant only for displaying data (read-only); users can be engaged in managing the table views to insert, update, delete, and reorder the table view cells. Thanks to UITableView, these kinds of operations are not difficult to implement and with just simple lines of code, you can bring all these awesome features to your app. In this section, we will see how to trigger the editing mode in table view to delete or reorder cells. We will see how to insert new rows at runtime to the table view with animations as well.

Getting ready
