Unable to cast UIImage in swift iOS 8 Extension

Question

I have a strange problem, I am trying to build an action extension that will scan barcode from the image provided. Here is the code.

override func viewDidLoa         


        

Answer 1

Getting image as

<UIImage: 0x16ecb410>, {100, 100}

It cannot be casted as NSURL and getting nil in the following expression.

imageView.image = UIImage(data: NSData(contentsOfURL: image as NSURL)!)!

Answer 2

U need to do like this

    if let strongImageView = weakImageView {

                   if let imageURL = image as? NSURL{

                 strongImageView.image = UIImage(data:NSData(contentsOfURL: imageURL)!)

                    }else{

                      strongImageView.image = image as? UIImage
                    }

                }

For Clarification I added Full Code Please refer, It worked for me

override func viewDidLoad() {
super.viewDidLoad()


// Get the item[s] we're handling from the extension context.

// For example, look for an image and place it into an image view.
// Replace this with something appropriate for the type[s] your extension supports.
var imageFound = false
for item: AnyObject in self.extensionContext!.inputItems {
    let inputItem = item as! NSExtensionItem
    for provider: AnyObject in inputItem.attachments! {
        let itemProvider = provider as! NSItemProvider
        if itemProvider.hasItemConformingToTypeIdentifier(kUTTypeImage as String) {
            // This is an image. We'll load it, then place it in our image view.
            weak var weakImageView = self.imageView
            itemProvider.loadItemForTypeIdentifier(kUTTypeImage as String, options: nil, completionHandler: { (image, error) in
                NSOperationQueue.mainQueue().addOperationWithBlock {


                if let strongImageView = weakImageView {

                       if let imageURL = image as? NSURL{

                     strongImageView.image = UIImage(data:NSData(contentsOfURL: imageURL)!)

                        }else{

                          strongImageView.image = image as? UIImage
                        }

                    }


                }
            })

            imageFound = true
            break
        }
    }

    if (imageFound) {
        // We only handle one image, so stop looking for more.
        break
    }
}
}

the thing is that image is not UIImage, it's NSURL.

Change code to this one:

imageView.image = UIImage(data: NSData(contentsOfURL: image as NSURL)!)!
