TableView implemented methods no grouping of cells

#pragma mark-table View data source-(Nsinteger) TableView: (UITableView *) TableView numberofrowsinsection: (Nsinteger) section{    return self.contacts.count;} -(UITableViewCell *) TableView: (UITableView *) TableView Cellforrowatindexpath: (Nsindexpath *) indexpath{    //1. Create cell    Mjcontactcell *cell = [Mjcontactcell Cellwithtableview:tableview];       2. Set the cell data    cell.contact = Self.contacts[indexpath.row];        return cell;}

Refresh of TableView:

* Local Refresh (use premise: Before and after the refresh, the number of model data is unchanged)

-(void) Reloadrows: (Nsarray *) indexpaths withrowanimation: (uitableviewrowanimation) animation;

* Local deletion (use premise: number of model data reduction = = Indexpaths length)

-(void) Deleterowsatindexpaths: (Nsarray *) indexpaths withrowanimation: (uitableviewrowanimation) animation;

The left swipe calls the Commiteditingstyle method Commiteditingstyle to determine whether to add or remove

Let TableView into edit state

[Self.tableview setediting:!self.tableview.isediting Animated:yes];

When the Editstyleforrowatindexpath is implemented, this method is called when the edit is clicked, which asks the state of the edit
