i've uitableviewdatasource maintains sections of data items presented uitableview instance. table view editable, allowing insertion , deletion of rows , sections, , changes on view should written data source. after reading through apple documents, can deal insertion , deletion on rows sending message tableview:commiteditingstyle:forrowatindexpath: data source.

but, however, can't figure out standard way feedback changes on sections data source. please kindly help.

the delegate method tableview:commiteditingstyle:forrowatindexpath: called table view tell user has done (what have added / removed). responsibility of code make appropriate changes model , reload table view.

the simplest way reload call reloaddata, , have more specific options reloading / inserting / removing individual rows or sections - ui perspective , table view requires have updated model before call of these methods or table view throw exception.
