Implementing UIImagePickerController in Swift - ios

Question

The application runs just fine and allows me to select a photo. However, when I go to select a different photo the pickAnImage button won't work. What is the best way to allow the user to select a different image to view? Any help is appreciated.
import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate,UINavigationControllerDelegate {
#IBOutlet weak var imageView: UIImageView!
let imagePicker = UIImagePickerController()
#IBAction func pickAnImage(sender: AnyObject) {
imagePicker.allowsEditing = false
imagePicker.sourceType = .PhotoLibrary
self.presentViewController(imagePicker, animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
imageView.contentMode = .ScaleAspectFit
self.imageView.image = pickedImage
}
dismissViewControllerAnimated(true, completion: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
imagePicker.delegate = self
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

try this code :
import MobileCoreServices
class SecondViewController: UIViewController,UINavigationControllerDelegate, UIImagePickerControllerDelegate {
#IBOutlet var img:UIImageView!=nil
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning()
{
super.didReceiveMemoryWarning()
}
#IBAction func buttonTapped(AnyObject)
{
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.PhotoLibrary){
println("Button capture")
var imag = UIImagePickerController()
imag.delegate = self
imag.sourceType = UIImagePickerControllerSourceType.PhotoLibrary;
//imag.mediaTypes = [kUTTypeImage];
imag.allowsEditing = false
self.presentViewController(imag, animated: true, completion: nil)
}
}
func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!) {
let selectedImage : UIImage = image
//var tempImage:UIImage = editingInfo[UIImagePickerControllerOriginalImage] as UIImage
img.image=selectedImage
self.dismissViewControllerAnimated(true, completion: nil)
}
}
