How to get the edited image from UIImagePickerController in Swift?

Question

I have seen and read the documents of Apple where they have clearly mentioned about the key UIImagePickerControllerEditedImage. But when I am running my following code, I am not getting that key in the Dictionary. What is the reason behind this?

My Code:

func imagePickerController(picker: UIImagePickerController!, didFinishPickingMediaWithInfo info:NSDictionary!)
    {
        println(info)

        //var tempImage:UIImage = info[UIImagePickerControllerOriginalImage] as UIImage
        var tempImage:UIImage? = info[UIImagePickerControllerEditedImage] as? UIImage

        profileButton.setImage(tempImage, forState: UIControlState(0))

        self.dismissViewControllerAnimated(true, completion:nil)

    }

println(info) prints:

{
    UIImagePickerControllerMediaType = "public.image";
    UIImagePickerControllerOriginalImage = "<UIImage: 0x178295d60> size {960, 960} orientation 0 scale 1.000000";
    UIImagePickerControllerReferenceURL = "assets-library://asset/asset.JPG?id=2DDCE06B-6082-4167-A631-B3DF627055DF&ext=JPG";
}

FYI, I am picking image from Library and I tried from Camera also, but this key is still not coming but the other data about image is coming. And I am using iOS8.0 build SDK.

So how can I use UIImagePickerControllerEditedImageif there is no such key coming in the dictionary.

Solution 1

SWIFT 3.0:

Add UINavigationControllerDelegate and UIImagePickerControllerDelegate

var imagePicker = UIImagePickerController()

@IBAction func btnSelectPhotoOnClick(_ sender: UIButton)
{
    let alert = UIAlertController(title: "Choose Image", message: nil, preferredStyle: .actionSheet)
    alert.addAction(UIAlertAction(title: "Camera", style: .default, handler: { _ in
        self.openCamera()
    }))

    alert.addAction(UIAlertAction(title: "Gallery", style: .default, handler: { _ in
        self.openGallary()
    }))

    alert.addAction(UIAlertAction.init(title: "Cancel", style: .cancel, handler: nil))

    imagePicker.delegate = self
    self.present(alert, animated: true, completion: nil)
}
func openCamera()
{
    if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.camera))
    {
        imagePicker.sourceType = UIImagePickerControllerSourceType.camera
        imagePicker.allowsEditing = true
        self.present(imagePicker, animated: true, completion: nil)
    }
    else
    {
        let alert  = UIAlertController(title: "Warning", message: "You don't have camera", preferredStyle: .alert)
        alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
        self.present(alert, animated: true, completion: nil)
    }
}
func openGallary()
{
    imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
    imagePicker.allowsEditing = true
    self.present(imagePicker, animated: true, completion: nil)
}


func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    picker.dismiss(animated: true, completion: nil)
//You will get cropped image here..
    if let image = info[UIImagePickerControllerEditedImage] as? UIImage
    {
        self.imageView.image = image
    }   
}

You can do it like this.

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {

    let image = info[UIImagePickerControllerEditedImage] as UIImage
}

Solution 3

I found the cause of the issue! Its because of the property "allowsEditing" which was set to false! I have changed that to true and now it is working fine.

Solution 4

Swift 4.2

if let editedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage {
        // Use editedImage Here
    }

You are fetching value for key "UIImagePickerControllerEditedImage" but its not present in the dictionary "info". This is the problem I am facing!

I have tested this on an iPad with iOS 7 and simulator with iOS 8 and it works as well as shows the UIImagePickerControllerEditedImage when you println("\(info)") I did notice a difference in the way things are printed when changing didFinishPickingMediaWithInfo info: [NSObject : AnyObject] to didFinishPickingMediaWithInfo info:NSDictionary! do you get some kind of error if you use the above code? What version of Xcode are you using?

Dude! I have mentioned the response also in my question and I also mentioned that base SDK is 8.0 so obviously I am using xcode 6X. BTW I am using XCode 6.1 (not Beta)
