Answer 1

call

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath  

this method with from another class... with editing style set to UITableViewCellEditingStyleDelete

provided you have implement the same method in your previous class...

Answer 2

Pass a reference to your initial view controller with the table to the 2nd controller with you initialize and push it. Then you will be able to call any public methods on that view controller. This will allow you to define a method like -(void)deleteIt; and call that directly from the other controller. Also, if you need to track which cell element was clicked, pass the index along also.

EDIT

To pass data to the new view controller, you can do:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    NextViewController *nvCon = [[NextViewController alloc] initWithNibName:@"NextViewController" bundle:nil];
    nvCon.rootViewCon = self;
    nvCon.selectedIndex = indexPath;
    [self.navigationController pushViewController:nvCon animated:YES];
    [nvCon release];
}

Then call a public method on rootViewCon to initiate the delete. You can pretty much just copy the boilerplate code used for deleting table view cells here. There are many references on SO and in the Apple docs.
