title: UILabel positioning
body: <p>I will have several UILabels laid out horizontally and centered in a view.  Based on the users selection, there will be either 3, 5, or 7 labels.  </p>
  
  <p>I am wanting to keep the labels centered in each case.  </p>
  
  <p>Example:</p>
  
  <pre><code>        L1 L2 L3
       L1 L2 L3 L4 L5
    L1 L2 L3 L4 L5 L6 L7 
  </code></pre>
  
  <p>L1 is the same in each case and so on, just showing or hidding the others as needed.  Each line represents a unique case.  </p>
  
  <p>Trying to use constraints for each label seems like a big job. Is there a better way to do this???</p>
