1.删除行

首先创建编辑按钮

UIBarButtonItem * right = [[UIBarButtonItem alloc]initWithTitle:@"编辑" style:(UIBarButtonItemStylePlain) target:self action:@selector(didClickRightBarButtonItemAction:)];

-(void)didClickRightBarButtonItemAction:(UIBarButtonItem *)button{    NSLog(@"%@",button);   // _isEditing = !_isEditing;    if (_isEditing) {        NSLog(@"bianji =  %d",_isEditing);        _isEditing = NO;//没有进入编辑状态                button.title = @"编辑";    }else{        NSLog(@"wanc =  %d",_isEditing);        _isEditing = YES;//进入编辑状态        button.title = @"完成";    }        //tableView进入编辑状态    //默认所有的行都可以被编辑,编辑样式默认都是删除    [_listTableView setEditing:_isEditing animated:YES];}

//是否可以编辑,当某一行可以删除时才出现-(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{    //当没有分区时编辑不执行    if (indexPath.section ==0) {        return NO;    }    return YES;}

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{    if (editingStyle == UITableViewCellEditingStyleDelete) {       // NSLog(@"%s,%d",__FUNCTION__,__LINE__);                //修改数据源,即删除数据源中的某条数据        NSMutableArray * oneGoupArray = [_allGroupArray objectAtIndex:indexPath.section];                        //如果删除某行cell,cell刚好是section最后一条数据时不再删除cell,直接删除section        if (oneGoupArray.count == 1) {            //删除section            NSLog(@"indexPath = %ld",indexPath.section);            [_allGroupArray removeObjectAtIndex:indexPath.section];            NSLog(@"indexPath2 = %ld",indexPath.section);            [_listTableView deleteSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationRight];             NSLog(@"indexPath3 = %ld",indexPath.section);        }else{           [oneGoupArray removeObjectAtIndex:indexPath.row];       //tableview删除某行        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationRight];        }    }}
