title: How can I get images to appear in UI PickerView Component in Swift?
body: <p>I am trying to use images in a Swift PickerView.  I don't know how to get the images to actually appear in the component.  I know how to do this using Strings with the titleForRow function but I don't know how to do this using images.  Here is my code so far:</p>
  
  <pre><code>import UIKit
  class ViewController: UIViewController, UIPickerViewDelegate {
  
      @IBOutlet weak var pickerView: UIPickerView!
  
  
      var imageArray: [UIImage] = [UIImage(named: "washington.jpg")!,
          UIImage(named: "berlin.jpg")!, UIImage(named: "beijing.jpg")!,
          UIImage(named: "tokyo.jpg")!]
  
  
  
      override func viewDidLoad() {
          super.viewDidLoad()
          // Do any additional setup after loading the view, typically from a nib.
      }
  
      override func didReceiveMemoryWarning() {
          super.didReceiveMemoryWarning()
          // Dispose of any resources that can be recreated.
      }
  
  
      // returns the number of 'columns' to display.
      func numberOfComponentsInPickerView(pickerView: UIPickerView) -&gt; Int{
  
          return 1
  
      }
  
      // returns the # of rows in each component..
      func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -&gt; Int {
  
          return imageArray.count
      }
  
  
  
  }// end of app
  </code></pre>
