How to get file name in UIImagePickerController with Asset library?

Question

I want to get the file name from UIImagePickerController. I do not want to use ALAssetLibrary because it is deprecated in iOS 9. I have used the following code

Answer 1

Here is how I did it in swift 4

if let url = info[UIImagePickerController.InfoKey.imageURL] as? URL {
        fileName = url.lastPathComponent
        fileType = url.pathExtension
    }

Answer 2

You can try this for iOS 11

 func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    if let asset = info[UIImagePickerControllerPHAsset] as? PHAsset {
        if let fileName = (asset.value(forKey: "filename")) as? String {
            //Do your stuff here
        }
    }

    picker.dismiss(animated: true, completion: nil)
}

Make sure you add this NSPhotoLibraryUsageDescription to your Infor.plist

Answer 3

    let fileName = (info[.imageURL] as? URL)?.lastPathComponent

Answer 4

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    var selectedFileName = ""
    if #available(iOS 11.0, *) {
        if let imageUrl = info[.imageURL] as? URL {
            selectedFileName = imageUrl.lastPathComponent
        }
    } else {
        if let imageURL = info[.referenceURL] as? URL {
            let result = PHAsset.fetchAssets(withALAssetURLs: [imageURL], options: nil)
            if let firstObject = result.firstObject {
                let assetResources = PHAssetResource.assetResources(for: firstObject)
                selectedFileName = assetResources.first?.originalFilename
            }
        }
    }

    picker.dismiss(animated: true, completion: nil)
}

Swift 5, iOS 11+

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    let photo = info[.phAsset] as? PHAsset
    let filename = photo?.value(forKey: "filename") as! String
}

I will suggest you to use Photos Framework to get the name of the image, below is the code to get name of selected image

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    if let imageURL = info[UIImagePickerControllerReferenceURL] as? URL {
        let result = PHAsset.fetchAssets(withALAssetURLs: [imageURL], options: nil)
        let asset = result.firstObject
        print(asset?.value(forKey: "filename"))

    }

    dismiss(animated: true, completion: nil)
}
