title: Remove UILabel from superview
body: <p>I have an application that is written in Rubymotion. I am adding a label to the subView of the view. When I first call my method I want to remove any UILabel's form the superView so I can write new text over that same position.</p>
  
  <pre><code>class CalorieIntakeController &lt; UIViewController
    @label = UILabel.new
  
    @label.frame = [[0,270],[self.view.frame.size.width, 50]]
    @label.text = "Text goes here"
    self.view.addSubview(@label)
  end
  </code></pre>
  
  <p>I am trying to figure out how to use ruby to find if there is already a UILabel present.</p>
