Getting the file path of iOS image for use in Unity

Question

I need to get a file path for an iOS image to use it for a project I'm working on in Unity. So far I have this code:

#pragma mark - UIImagePickerControllerDelegate
// This method is called when an image has been chosen from the library or taken from the camera.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *, id> *)info
{
    NSString *type = [info objectForKey:UIImagePickerControllerMediaType];
    NSLog(@"type=%@",type);
    if ([type isEqualToString:(NSString *)kUTTypeImage])
    {
        NSURL* imageURL = (NSURL *)[info valueForKey:UIImagePickerControllerReferenceURL];
        NSString *urlString = [imageURL absoluteString];

        const char* cp = [urlString UTF8String];
        if(cp)
            strcpy(image_path, cp);
        else
        {//If the image path is unasigned give ERROR instead
            char* error = "ERROR";
            strcpy(image_path, error);
        }
    }

    [self dismissViewControllerAnimated:YES completion:NULL];

    // UnitySendMessage("GameObject", "VideoPicked", video_url_path);
    UnitySendMessage(callback_game_object_name, callback_function_name, image_path);
}

This however returns the image address in a format similar to the following:

assets-library://asset/asset.JPG?id=92C96E1D-F714-49E6-8074-5B5980FF944F&ext=JPG

Which as far as I can tell is only useful for iPhone libraries, is there a way to get its actual path, or am completely going down the wrong route?

As a side note the Unity code is completely fine, can get unity to receive the string etc. but it doesn't know what to do with it.

EDIT: This function got it to work for me thanks to Pankaj for his response

// This method is called when an image has been chosen from the library or taken from the camera.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *, id> *)info
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:@"setName.png"];

    //save image here and then use that imagePath
    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
    if ([mediaType isEqualToString:@"public.image"]){
        UIImage *editedImage = [info objectForKey:UIImagePickerControllerEditedImage];
        NSData *imageData = UIImagePNGRepresentation(editedImage);
        [imageData writeToFile:imagePath atomically:YES];
    }
    NSLog(@"imagePath=%@",imagePath);
    const char* cp = [imagePath UTF8String];
    strcpy(image_path, cp);

    [self dismissViewControllerAnimated:YES completion:NULL];

    UnitySendMessage(callback_game_object_name, callback_function_name, image_path);
}

Get image from PickerView and then store it in document directory then use that path for Unity.

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:@"setName.png"];

//save image here and then use that imagePath
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:@"public.image"]){
    UIImage *editedImage = [info objectForKey:UIImagePickerControllerEditedImage];
    NSData *imageData = UIImagePNGRepresentation(editedImage);
    [imageData writeToFile:imagePath atomically:YES];
}

UnitySendMessage(callback_game_object_name, callback_function_name, imagePath);
