How do I get the original filename of the image selected by UIImagePickerController?

I have implemented a delegate method and can access the selected UIImage like:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage *pickedImage = [info valueForKey:UIImagePickerControllerOriginalImage];

I want to store it in a directory, but I need the filename. So instead of just choosing an arbitrary filename, it makes sense to choose the same filename as the image.

Is there a way to extract it from this information dictionary?

You can use the UIImagePickerControllerReferenceURL

information dictionary value instead UIImagePickerControllerOriginalImage

. This should indicate the URL of the original media element.



This will give you back an object NSURL

that you can use to create your new filename.

  • Use the ALA Assets library infrastructure

  • Use below code

    
    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
    [library writeImageToSavedPhotosAlbum:image.CGImage orientation:(ALAssetOrientation)image.imageOrientation completionBlock:^(NSURL *assetURL, NSError *error )
    {
       [library assetForURL:assetURL resultBlock:^(ALAsset *asset )
       {
         ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *imageAsset)
         {
             ALAssetRepresentation *imageRep = [imageAsset defaultRepresentation];
             NSLog(@"reference image filename picking from camera: %@", [imageRep filename]);
         };
         ALAssetsLibrary* assetslibrary = [[ALAssetsLibrary alloc] init];
         [assetslibrary assetForURL:assetURL resultBlock:resultblock failureBlock:nil];
       }
       failureBlock:^(NSError *error )
       {
           NSLog(@"Error loading asset");
       }];
    }];


      
    
        
        
        
      
    
    
    imageView.image = [info objectForKey:UIImagePickerControllerEditedImage];
imageView.contentMode = UIViewContentModeScaleAspectFit;
