title: update Label with Textfield inside UICollectionViewCell
body: <p>So I have a CollectionView inside my normal ViewController and if I select a cell and enter something in my textField and press the save Button it should update the nameLabel but I don't know how I can do that. Does anybody have a solution for this?</p>
  
  <p>This is my current code:</p>
  
  <pre><code>    private let reuseIdentifier: String = "Item"
  
  class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate, UIGestureRecognizerDelegate, UITextFieldDelegate {
  
      override func viewDidLoad() {
          super.viewDidLoad()
          ItemCollection.delegate = self
      }
  
  
  
      func textEnter() {
          var text = textField.text
  
          let indexPath = NSIndexPath()
          let cell = ItemCollection.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! ItemCell
  
          cell.nameLabel.text = text
  
      }
  
      @IBAction func save(sender: AnyObject, cell: UICollectionViewCell) {
          textEnter()
      }
  
      @IBOutlet weak var textField: UITextField!
      @IBOutlet weak var ItemCollection: UICollectionView!
  
  
      func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -&gt; Int {
          return 2
      }
  
      func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -&gt; UICollectionViewCell {
          let cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! ItemCell
  
          cell.backgroundColor = UIColor(red: 0/256, green: 128/256, blue: 255/256, alpha: 0.66)
          cell.nameLabel.text = "Test1"
          return cell
      }
  
      func collectionView(collectionView: UICollectionView, shouldSelectItemAtIndexPath indexPath: NSIndexPath) -&gt; Bool {
          return true
      }
  
  }
  </code></pre>
  
  <p>My Cell: </p>
  
  <pre><code>class ItemCell: UICollectionViewCell {
  
      @IBOutlet weak var nameLbl: UILabel!
  
  }
  </code></pre>
