Answer 1

    [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:index] withRowAnimation:UITableViewRowAnimationNone];

whenever you remove or add a table row in updates..the table view reloads and ask the datasource for the number of rows based on which cell is animated to position.

you are removing row from table but not from datasource..so rows are deleted but your datasource still points out that no row is deleted..20 objects are still there. your data source will be something like

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return MyDataModel.count; // 
}

so you need to remove or add new data in datasource also..something like this

   NSIndexPath *index = [NSIndexPath indexPathForRow:i inSection:0];
   [MyDataModel removeObjectAtIndex:index.row];
   [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:index] withRowAnimation:UITableViewRowAnimationNone];
