title: Button not responding to taps inside TableViewCell
body: <p>I have a custom TableViewCell with a button. Before switching to dynamic cells, this button worked fine. However, now the button is unselectable.</p>
  
  <p>The button doesn't even highlight on touch.</p>
  
  <p>The best part? If i disable AutoLayout, while the button appears at the very top of the viewcontroller, almost too small to touch... it works</p>
  
  <p>Event attempting to remove autolayout and programmatically changing the position of the button within the cell like this, doesn't work: </p>
  
  <p>Button.frame.origin.x = self.contentView.frame.width / 2</p>
  
  <p>The code for my button:</p>
  
  <pre><code>class HotelRateCell: UITableViewCell {
  
     @IBOutlet weak var hotelRateTitle: UILabel!    
     @IBOutlet weak var hotelRatePrice: UILabel!    
     @IBOutlet weak var type: UILabel!    
     @IBOutlet weak var details: UILabel!
     @IBOutlet weak var button: UIButton!
  
     override func awakeFromNib() {
        super.awakeFromNib()
        //tried both enabled and disabled
        self.contentView.userInteractionEnabled = true
     }
  
     override func setSelected(selected: Bool, animated: Bool) {
       super.setSelected(selected, animated: animated)   
     }
  }
  </code></pre>
  
  <p>And the code for the actual action</p>
  
  <pre><code>override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCell {
      let cell: HotelRateCell = tableView.dequeueReusableCellWithIdentifier("HotelRateCell", forIndexPath: indexPath) as! HotelRateCell
  
      cell.reservationButton.tag = indexPath.row
  
      cell.button.addTarget(self, action: "reservationButton:", forControlEvents: .TouchUpInside)
      cell.reservationButton.addTarget(self, action: "reservationButton:", forControlEvents: UIControlEvents.TouchUpInside)
  
      return cell
  }
  
   func reservationButton(sender: UIButton!) {
      if sender.tag == 0 {
      UIApplication.sharedApplication().openURL(NSURL(string: "http://reddit.com")!)
          println("rservation button pressed")
  
      }
  }
  </code></pre>
