    UIImagePickerControllerOriginalImage returns only the image's data, with no reference to its local storage. I haven't used it myself but I guess what you are looking for is

    NSURL* localUrl = (NSURL *)[info valueForKey:UIImagePickerControllerReferenceURL];
    

    At least, it's the only way I know of to retrieve any URL.

    To retrieve the image, have a look at this question. But also keep in mind, that you already have the image retrieved with

    UIImage* image=(UIImage*)[info objectForKey:@"UIImagePickerControllerOriginalImage"];
    

    so ask yourself if you really need this.

    Swift 3.0, You can get imageData from referenceURL by following way

    let url = URL(string: "assets-library://asset/asset.JPG?id=1000000007&ext=JPG")
    let asset = PHAsset.fetchAssets(withALAssetURLs: [url], options: nil)
    guard let result = asset.firstObject else {
      return nil
    }
    let imageManager = PHImageManager.default()
    var imageData: Data? = nil
    imageManager.requestImageData(for: result, options: nil, resultHandler: { (data, string, orientation, dict) in
      imageData = data
    })
