Is it possible to configure a UITableView to allow multiple-selection?

Following property should work fine if you are developing app for iOS5.0+

self.tableView.allowsMultipleSelection = YES;

The best way to do this would be to a checkmark per selected row.

You can do that by setting the accessoryType on the selected UITableViewCell instances to UITableViewCelAccessoryCheckmark.

To deselect the row, set it back to UITableViewCellAccessoryNone.

To enumerate which cells/rows were selected (say, upon clicking a button), simply iterate over the cells of the table looking for UITableViewCellAccessoryCheckmark. Or, manage some NSSet or the like in your table view delegate in the "did select" delegate methods.

Use the following code to set up the cell accesory types:

    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewCell *thisCell = [tableView cellForRowAtIndexPath:indexPath];


    if (thisCell.accessoryType == UITableViewCellAccessoryNone) {
        thisCell.accessoryType = UITableViewCellAccessoryCheckmark;

    }else{
        thisCell.accessoryType = UITableViewCellAccessoryNone;

    }
}

- (UITableViewCellAccessoryType)tableView:(UITableView *)tableView accessoryTypeForRowWithIndexPath:(NSIndexPath *)indexPath {

//add your own code to set the cell accesory type.
return UITableViewCellAccessoryNone;
}
