title: How to set a tap for imageview array in Swift/Xcode
body: <p>I am trying to set tap listeners for each imageview from my imageview array and print when one is selected. Ideally I would like each imageview to have its on listener - such as "imageview 2 was selected." Thanks!</p>
  
  <pre><code>class ViewController2: UIViewController {
  
  @IBOutlet weak var scrollView: UIScrollView!
  
  var index: Int = 0
  
  var images: [UIImage] = [UIImage(named: "image1.png")!, UIImage(named: "image2.png")!, UIImage(named: "image3.png")!, UIImage(named: "image4.png")!, UIImage(named: "image5.png")!, UIImage(named: "image6.png")!, UIImage(named: "image7.png")!, UIImage(named: "image8.png")!, UIImage(named: "image9.png")!, UIImage(named: "image10.png")!, UIImage(named: "image11.png")!, UIImage(named: "image12.png")!, UIImage(named: "image13.png")!, UIImage(named: "image14.png")!, UIImage(named: "image15.png")!, UIImage(named: "image16.png")!, UIImage(named: "image17.png")!, UIImage(named: "image18.png")!, UIImage(named: "image19.png")!, UIImage(named: "image20.png")!, UIImage(named: "image21.png")!, UIImage(named: "image22.png")!, UIImage(named: "image23.png")!, UIImage(named: "image24.png")!, UIImage(named: "image25.png")!, UIImage(named: "image26.png")!, UIImage(named: "image27.png")!, UIImage(named: "image28.png")!, UIImage(named: "image29.png")!, UIImage(named: "image30.png")!]
  
  var imageView: [UIImageView] = []
  
  
  
  override func viewDidLoad() {
      super.viewDidLoad()
      // Do any additional setup after loading the view, typically from a nib.
  
      let screenSize: CGRect = UIScreen.mainScreen().bounds
      let screenWidth = screenSize.width
      //let screenHeight = screenSize.height
  
      let numWidth: CGFloat = 3
      let numHeight: CGFloat = 10
      self.scrollView.frame.size.width = screenWidth
      let width: CGFloat = (self.scrollView.frame.size.width - (numWidth + 1))/3
  
      var tap = UITapGestureRecognizer(target: self, action: Selector("tappedMe"))
  
      for var i:CGFloat = 0; i &lt; 3; ++i{
          for var j:CGFloat = 0; j &lt; 10; ++j {
  
              let image: UIImage = images[index]
              imageView.append(UIImageView(image: image))
              imageView[index].frame = CGRectMake(width*i, width*j, width, width)
              self.scrollView.addSubview(imageView[index])
  
              imageView[index].addGestureRecognizer(tap)
              imageView[index].userInteractionEnabled = true
  
              index++
          }
      }
      scrollView.contentSize.height = (width)*numHeight
  
  
  }
  
  override func didReceiveMemoryWarning() {
      super.didReceiveMemoryWarning()
      // Dispose of any resources that can be recreated.
  }
  
  func imageTapped(img: AnyObject)
  {
      // Your action
      print("tapped")
  }
