UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:

gistfile1.rb

class AppDelegate

  def application(application, didFinishLaunchingWithOptions:launchOptions)
    @window = UIWindow.alloc.initWithFrame UIScreen.mainScreen.bounds
    @window.rootViewController = ContactsController.alloc.init
    @window.makeKeyAndVisible

    true
  end

end

class ContactsController < UITableViewController

  def tableView(tableView, numberOfRowsInSection:section)
    3
  end

  def tableView(tableView, celForRowAtIndexPath:indexPath)
    cell = UITableViewCell.alloc.initWithStyle UITableViewCellStyleDefault, reuseIdentifier:nil
    cell.textLabel.text = 'stuff!'
    cell
  end

end

def tableView(tableView, celForRowAtIndexPath:indexPath) -- missing the second l in "cell"?
