title: Achieve button click in UICollectionView
body: <p>Is there a way I can get the button click event from a button inside a <code>UICollectionViewCell</code>? I used a nib to populate the collection view, the cell has the button but its action is not getting called.  I think the problem is with the delegate being called. How can I fix this?</p>
  
  <p>How I created : </p>
  
  <ol>
  <li>Added an empty nib, created a collection view cell </li>
  <li>Added a .h and .m file and made the cell nib's files owner as the class created</li>
  <li>Wrote an action in the class.</li>
  <li>Connected the button to the action</li>
  </ol>
  
  <p>Is there a way I can get the action?
  What  am I doing wrong?</p>
