title: iOS - Long Press Gesture Recognizer for UIButton in UITableViewCell
body: <p>I have a <code>UITableViewCell</code> with 3 <code>UIButton</code>s in it used to decrement a counter. On long press one of the buttons, I would like to set the counter to 0.</p>
  
  <p>Doing this in Interface Builder, I dragged a <code>Long Press Gesture Recognizer</code> onto my <code>button</code> and connected the selector to an <code>IBAction</code> specified in my <code>UITableViewCell.m</code>.</p>
  
  <p>That's all I did but when I run the app it gives the following error.</p>
  
  <pre><code>'NSInternalInconsistencyException', 
  reason: 'invalid nib registered for identifier (editQuotaCell) 
  - nib must contain exactly one top level object which must be a UITableViewCell instance'
  </code></pre>
  
  <p>Am I missing any steps?</p>
