title: numberOfRowsInSection / 3 - Only returning 15 images and not 16 or 17 as they're not divisible by 3
body: <p>I am querying images from parse to display in my tableViewCell which has 3 imageView inside of it. So If I have 15 images I will get 5 TableView rows and all the images will display correctly.</p>
  
  <p>But if I have 16 or 17 image, which aren't a multiple of 3 the images are not shown, which is quite logical as i have add my query count divided by 3. But I have been recomended a method by another very helpful user on here @Wottle that should fix this issue, but it doesn't seem to be working correctly! Here is my code below, I hope someone is able to help me!</p>
  
  <p>And I am grateful for your time.</p>
  
  <p>this function should allow me to visualize the images even if they'r enot a multiple of 3.</p>
  
  <pre><code> func roundUp(value: Double) -&gt; Int {
          if value == Double(Int(value)) {
              return Int(value)
          } else if value &lt; 0 {
              return Int(value)
          } else {
              return Int(value) + 1
          }
      }
  
      func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int
      {
          return roundUp( Double(imageArray.count / 3) )
  
  
  
      }
  </code></pre>
  
  <p>And here is my cellForRowAtIndexPath:</p>
  
  <pre><code> func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCell
       {
          var counter = (indexPath.row * 3)
  
        let cell = tableView.dequeueReusableCellWithIdentifier("cell") as! ProfileTableViewCell
  
  
          for imageView in cell.threeImages {
              imageView.image = UIImage(named: "ImagePlaceHolder")
  
              if counter &lt; imageArray.count {
              let finalImage = imageArray[counter++]["image"]
              finalImage!.getDataInBackgroundWithBlock {
                  (imageData: NSData?, error: NSError?) -&gt; Void in
                  if error == nil {
                      if let imageData = imageData {
                          imageView.image = UIImage(data:imageData)
  
                      }}}}
  </code></pre>
  
  <p>Best regards.</p>
