Unable to pass image taken from camera to another viewcontroller - ios

Question

I have a button to take an image . I wish to pass the image taken from camera to another view controller.The code for first viewcontroller is shown below.
#IBAction func takePhoto(sender: AnyObject)
{ let picker = UIImagePickerController()
picker.delegate = self
picker.sourceType = .Camera
presentViewController(picker, animated: true,completion : nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])
{
TakenImage = info[UIImagePickerControllerOriginalImage] as? UIImage ; dismissViewControllerAnimated(true, completion: nil )
let controller = self.storyboard!.instantiateViewControllerWithIdentifier("NoteDetailViewController") as! NoteDetailViewController
controller.takinPhoto = true
if (note != "")
{
controller.content = note
}
controller.imageFromCamera = TakenImage
if (self.tags != "")
{
controller.tagsTextField.text = self.tags
}
self.presentViewController(controller, animated: true, completion: nil)
}
#IBAction func save(sender: AnyObject)
{
UIImageWriteToSavedPhotosAlbum(TakenImage!, self, "image:didFinishSavingWithError:contextInfo:", nil)
}
func image(image: UIImage, didFinishSavingWithError error: NSError?, contextInfo:UnsafePointer<Void>)
{
if error == nil {
let ac = UIAlertController(title: "Saved!", message: "Your altered image has been saved to your photos.", preferredStyle: .Alert)
ac.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
presentViewController(ac, animated: true, completion: nil)
} else
{
let ac = UIAlertController(title: "Save error", message: error?.localizedDescription, preferredStyle: .Alert)
ac.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
presentViewController(ac, animated: true, completion: nil)
}
}
The code for my second viewcontroller is shown below
if (takinPhoto == true)
{
if (imageFromCamera != nil)
{
if let image1 = self.imageFromCamera
{
self.imageView2.image = image1
}
}
if (self.content != "")
{
self.contentTextField2.text = content
}
}
But image from camera is not appearing in the second viewcontroller.How can I solve this??

Updated answer.
I rewrote your code and was able to get it working locally. The main change was to use a different delegate method which is specific to photos.
#IBAction func takePhoto(sender: AnyObject) { let picker = UIImagePickerController()
picker.delegate = self
picker.sourceType = .Camera
presentViewController(picker, animated: true,completion : nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
takenImage = image
dismissViewControllerAnimated(true, completion: nil)
}
#IBAction func save(sender: AnyObject) {
UIImageWriteToSavedPhotosAlbum(takenImage!, self, #selector(ViewController.image(_:didFinishSavingWithError:contextInfo:)), nil)
}
func image(image: UIImage, didFinishSavingWithError error: NSError?, contextInfo:UnsafePointer<Void>) {
if error == nil {
let ac = UIAlertController(title: "Saved!", message: "Your altered image has been saved to your photos.", preferredStyle: .Alert)
ac.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
presentViewController(ac, animated: true, completion: nil)
} else {
let ac = UIAlertController(title: "Save error", message: error?.localizedDescription, preferredStyle: .Alert)
ac.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
presentViewController(ac, animated: true, completion: nil)
}
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if (segue.identifier == "saveTakenImage") {
let controller = segue.destinationViewController as! NoteDetailViewController
controller.takinPhoto = true
if (note != "") {
controller.content = note
}
controller.imageFromCamera = takenImage
if (self.tags != "") {
controller.tagsTextField.text = self.tags
}
}
}
